EXAM QUESTION
Q.Which of the following are Ethical Theories studied in the literature:
b. Mike’s Formalism, a correct choice is one in which each person follows an ethical route
c. Big Daddy’s Duty Ethics, a correct choice is one in which each person follows an ethical route.
d. Mill’s Utilitarianism, a correct choice is one that provides the least benefit to most of the people.
ANSWER: The correct answer is Locke’s Rights, a. Some may believe that Mill’s is correct; however, the statement is wrong and should be the “max benefit to most of the people”. Also answers b and c have incorrect names associated with them.
RED HOT EXAM TIP: Often times it is best to start by eliminating answers - a good technique to have in your arsenal.
Explanation: Here are the evaluations of each option:
a. Locke’s Rights
✔ Yes — This
is a real ethical theory.
John Locke is known for Rights Theory, where ethical choices must not
infringe on basic human rights (life, liberty, property).
The description is mostly correct.
b. Mike’s Formalism
✘ No — Not a
real ethical theory.
There is Kant’s Formalism (or Kantian Duty Ethics), but “Mike’s
Formalism” is not studied in ethics.
c. Big Daddy’s Duty Ethics
✘ No — Not a
real ethical theory.
There is Duty Ethics—mainly associated with Immanuel Kant—but
“Big Daddy’s Duty Ethics” is not an academic term.
d. Mill’s Utilitarianism
✘ No — This is a real ethical theory.
John Stuart Mill is a major figure in Utilitarianism.
But the description in the question is incorrect:
Utilitarianism aims for the greatest good (benefit) for the greatest number,
not the least benefit.
ANSWER: The correct answer is Locke’s Rights, a. Some may believe
that Mill’s is correct; however, the statement is wrong and should be the “max
benefit to most of the people”.
Final Answer
The ethical
theories actually studied in the literature are:
✅ a. Locke’s Rights

Section 9.2:
“Four Important Ethical Theories
- Mill’s Utilitarianism
- Kant’s Formalism (Duty Ethics)
- Locke’s Rights Ethics
- Aristotle’s Virtue Ethics
Eight difficult, realistic NPPE-style MCQs (two per theory), including applied and mixed-theory scenarios designed for higher cognitive challenge.
🧠 MILL’S UTILITARIANISM (Greatest Good for
Greatest Number)
An engineer must choose between two
wastewater treatment methods.
- Option A: Expensive but eliminates nearly all contaminants.
- Option B: Cheaper and provides 90% reduction, allowing the
city to fund other community programs.
She recommends Option B because
it benefits more citizens overall despite minor environmental compromise.
Which ethical theory best explains her
reasoning?
A. Kant’s formalism
B. Mill’s utilitarianism
C. Locke’s rights ethics
D. Aristotle’s virtue ethics
✅ Correct Answer: B
She maximizes collective benefit
(public welfare) rather than perfection — a utilitarian approach.
A mining project would create jobs for
500 workers but displace 10 families from ancestral land. The engineer supports
it, arguing the “overall happiness” outweighs limited harm.
Which weakness of
utilitarianism does this scenario highlight?
A. It ignores duty and moral intention.
B. It undervalues individual rights for the majority’s benefit.
C. It fails to consider professional codes.
D. It relies solely on metaphysical reasoning.
✅ Correct Answer: B
Utilitarianism risks justifying harm
to a few if the majority benefits.
⚖️ KANT’S FORMALISM (Duty Ethics /
Categorical Imperative)
An engineer
discovers a structural error that may not cause immediate failure but violates
design code.
The client insists not to report it since “it’s unlikely to cause problems.”
The engineer insists on reporting it because rules must be followed
universally.
Which principle
guides the engineer’s decision?
A. Maximizing public happiness
B. Acting from duty, not consequence
C. Protecting the client’s property rights
D. Achieving balance between extremes
✅ Correct
Answer: B
Kant’s duty
ethics emphasizes moral duty regardless of outcome — the “categorical
imperative.”
Q4.
Which theory would most strongly oppose this reasoning?
A. Mill’s utilitarianism
B. Locke’s rights ethics
C. Kant’s formalism
D. Aristotle’s virtue ethics
✅
Correct Answer: C
Kantian
ethics rejects lying even for good ends — moral actions must be universally
right.
Why?
Kantian ethics is grounded in the categorical imperative,
which states that actions must follow universal moral rules (e.g., “Never
lie”), regardless of consequences.
Even if lying brings good outcomes—like helping a charity—Kant rejects
using others as a means to an end.
So Kant’s formalism most strongly opposes the engineer’s justification.
Q.
Which theory would most
strongly support this reasoning?
The ethical theory that
justifies an action based on producing the greatest good for the greatest
number is:
A. Mill’s
utilitarianism
Why?
Mill’s utilitarianism focuses on maximizing total happiness or benefit.
Since the engineer believes the lie will secure a discount that helps a charity
and benefits many people, a utilitarian would justify the lie if it
increases overall welfare.
🧾 LOCKE’S RIGHTS ETHICS (Fundamental Human Rights)
Q5.
Which ethical
theory supports her stance?
A. Mill’s utilitarianism
B. Locke’s rights ethics
C. Kant’s duty ethics
D. Aristotle’s virtue ethics
✅ Correct
Answer: B
Locke’s theory
emphasizes inherent rights — life, liberty, and property — as fundamental and
non-negotiable.
Q6.
A planner objects, citing the vendors’ right to work and pursue economic
freedom.
Which ethical
theory aligns with the planner’s reasoning?
A. Mill’s utilitarianism
B. Kant’s formalism
C. Locke’s rights ethics
D. Aristotle’s virtue ethics
✅ Correct
Answer: C
This appeals to
Locke’s principle of individual liberty and economic rights.
🏛️ ARISTOTLE’S VIRTUE ETHICS
(Moral Character and the Golden Mean)
Q7.
- Hiding results protects the client.
- Full disclosure could cause public panic.
She chooses to release data with careful explanation to balance honesty with responsibility.
Which principle best describes her
approach?
A. Acting from categorical imperative
B. Applying the “Golden Mean” between extremes
C. Maximizing the greatest happiness
D. Upholding individual rights
✅ Correct Answer: B
Aristotle’s “Golden Mean” represents
moderation and moral balance between extremes (recklessness vs. cowardice).
Q. Why not option C?
Good question — here’s why Option C (maximizing the
greatest happiness) is not the best fit, even though it might
seem plausible.
Q. Why not option C?
Good question — here’s why Option C (maximizing the
greatest happiness) is not the best fit, even though it might
seem plausible.
✅ Why C is NOT the best answer
Utilitarianism (option C) focuses on
choosing the action that produces the greatest overall good or happiness
for the greatest number.
In this scenario, the engineer is not
primarily calculating overall happiness. She is not weighing:
·
How many people
panic vs.
·
How many people
benefit,
·
or which choice
produces the most total utility.
Instead, she is focusing on:
·
Honesty (a moral virtue)
·
Responsibility (another virtue)
·
And choosing a balanced
option between two moral extremes.
The emphasis is on character and balance,
not on outcome maximization.
✅ Why B
is the best answer
Option B refers to Aristotle’s Golden
Mean, which aims for a virtuous middle path between:
·
Deficiency (hiding data = lack of honesty)
·
Excess (full disclosure without explanation =
irresponsibility)
Her reasoning follows this exact pattern:
find the balanced, virtuous response that harmonizes
conflicting duties.
🔍 Summary
|
Option |
Why Not? |
|
C.
Maximizing greatest happiness |
Would
require her to calculate which option produces the most total good; the
scenario shows her aiming for a balanced moral response,
not a utility calculation. |
If the scenario explicitly stated she chose
the option because it caused the greatest overall
Q.8. Here is a revised version of the scenario so that utilitarianism (Option C) becomes the correct answer:
✅ Rewritten
Scenario (Utilitarianism as Correct Answer)
An environmental engineer discovers contamination in the
soil near a residential area.
• Hiding the results would protect her client’s reputation.
• Releasing the data might cause public fear and economic loss.
She decides to fully disclose the contamination because doing
so will protect the health and long-term well-being of the greatest number of
people, even though it will cause short-term discomfort and financial
harm.
Which ethical principle best describes her reasoning?
A. Acting from categorical imperative
B. Applying the “Golden Mean”
C. Maximizing the greatest happiness
D. Upholding individual rights
✅ Correct Answer: C.
Maximizing the greatest happiness
This version now clearly shows that she is
choosing the action that produces the greatest overall good,
even at a cost — which is classic utilitarian reasoning.
Q. Here are three rewritten versions
of the same scenario—each tailored so that a different ethical theory
becomes the correct answer.
✅ 1.
Kant’s Formalism (Categorical Imperative) —
An environmental engineer discovers
contamination data that could damage her client’s business if revealed. Although
releasing the data may cause public alarm and financial loss, she decides to
disclose everything because she believes telling the truth is a moral
duty that must be followed regardless of consequences.
Which principle best describes her
reasoning?
A. Acting from categorical imperative ✔️
B. Applying the “Golden Mean”
C. Maximizing the greatest happiness
D. Upholding individual rights
✅ 2.
Rights Ethics —
An environmental engineer finds contamination
near a residential neighbourhood.
Her client urges her to keep the findings confidential to prevent bad
publicity.
She insists on releasing the information because the public has a
fundamental right to know about risks to their health and safety, even
if disclosure harms the client’s business interests.
Which principle best describes her
reasoning?
A. Acting from categorical imperative
B. Applying the “Golden Mean”
C. Maximizing the greatest happiness
D. Upholding individual rights ✔️
✅ 3.
Virtue Ethics (Golden Mean) — Option B Correct
An environmental engineer uncovers
contamination that could worry the community.
She avoids both extremes—
• Hiding the results (a lack of honesty)
• Publishing raw data without explanation (a lack of prudence)
Instead, she releases the data with clear
interpretation so the public remains informed without unnecessary panic. This
reflects a balanced, virtuous approach.
Which principle best describes her
reasoning?
A. Acting from categorical imperative
B. Applying the “Golden Mean” ✔️
C. Maximizing the greatest happiness
D. Upholding individual rights
Q. What does option A mean?
Acting from the categorical
imperative means doing
what is morally right purely out of duty, following universal moral
rules, regardless of consequences.
This idea comes from Immanuel Kant.
Categorical
Imperative Means (Simple Explanation)
Kant argued that an action is morally right
when:
1.
You
follow a moral rule that could apply to everyone, without exception.
2.
You act out
of duty, not personal gain or
feelings.
3.
You treat
people as ends in themselves,
never merely as a means to an end.
Explanation
of option # 3
You treat people as ends in themselves, never merely as a means to an end.
T his statement comes from Immanuel Kant’s ethical theory,
specifically his Categorical Imperative. “Ends in themselves”
means that people have their own value, goals, rights, and dignity, and
you must respect those — not treat them like objects or tools for your own
purposes.
Simple meaning
When you treat
someone as an end in themselves, you:
- Recognize they are a full human being with their own
wishes and choices.
- Consider their wellbeing, not just your own.
- Respect their autonomy and freedom to decide.
- Do not manipulate, deceive, or exploit them.
“As a means to
an end” means using
someone only as a tool to achieve your own goal, without caring about
their own rights, choices, or wellbeing.
Clear explanation
When you treat
a person as a means to an end, you:
- Use them just to get something you want.
- Treat them like an instrument or object.
- Ignore their autonomy (their right to choose).
- Don’t consider their interests, dignity, or consent.
It’s basically using
people, rather than respecting them.
Simple example
- Lying to someone to get money from them.
- Pretending to be nice only because you want a
favour.
- Manipulating someone so they’ll help you.
- Using a coworker’s effort so you can take credit.
In all of
these, the person is just a means — a tool to reach your end
(your goal).
(Combined Scenario — Mixed Theories)
A transportation engineer faces two
options:
- Option A: Delay a bridge opening to meet every safety
standard (Kantian approach).
- Option B: Open early to relieve major traffic suffering
(Utilitarian approach).
After reflection, she chooses Option
A, explaining that “compromising safety erodes professional integrity and
virtue.”
Her reasoning combines which two
ethical frameworks?
A. Kant’s duty ethics and Aristotle’s virtue ethics
B. Locke’s rights ethics and Mill’s utilitarianism
C. Mill’s utilitarianism and Kant’s formalism
D. Aristotle’s virtue ethics and Locke’s rights ethics
✅ Correct Answer: A
She prioritizes moral duty (Kant) and
character integrity (Aristotle), valuing virtue over convenience.
🧩 Advanced NPPE Mixed-Theory Ethical Scenarios
A municipal engineer discovers that
delaying a bridge repair by one month would allow for a cheaper and more
complete reconstruction, saving taxpayer money. However, the bridge’s current
state poses a small but real safety risk.
She decides to close the bridge
immediately, even though the public will be angry and costs will increase.
Which theory best describes her
reasoning?
A. Mill’s Utilitarianism – maximizing benefit for most
B. Kant’s Formalism – acting from duty to protect safety regardless of cost
C. Locke’s Rights Ethics – defending the public’s right to travel freely
D. Aristotle’s Virtue Ethics – finding a balanced middle ground
✅ Correct Answer: B
The engineer follows her duty to ensure
safety as a universal obligation, even against majority opinion — a Kantian
principle.
Q2. (Collective Benefit
vs. Individual Rights)
A
renewable energy project will displace a few landowners but provide clean power
for 50,000 homes. The engineering team supports the project despite protests
from affected families.
Which
criticism of their reasoning is strongest?
A. They ignored professional duty to follow code.
B. They valued utilitarian benefit over Locke’s individual property rights.
C. They misapplied Kant’s categorical imperative.
D. They failed to act with Aristotle’s moral balance.
✅
Correct Answer: B
Utilitarian
logic can overlook the protection of basic rights (property, liberty) central
to Locke’s ethics.

Q3. (Professional Integrity Conflict)
A consultant is
asked to sign off on a design she did not review, to expedite approval for a
hospital construction. The client insists that “it’s only a formality, and
lives will be saved once the hospital opens.”
Which response
aligns most closely with professional ethics and Kant’s formalism?
A. Sign, since it achieves the greatest good.
B. Refuse, because truthfulness and professional duty must not be violated
regardless of outcomes.
C. Sign, provided the design meets safety standards.
D. Seek compromise to balance moral and practical outcomes.
✅ Correct
Answer: B
Kantian ethics
demands acting from duty and honesty, not consequence — signing without review
breaches categorical duty.
Q4. (Virtue and Professional Character)
An engineer
debates whether to disclose a client’s violation of environmental laws.
- Reporting would ruin the client
financially.
- Staying silent could harm the community.
After
reflection, she chooses to report the issue respectfully, balancing
courage with compassion.
Which theory
best fits her approach?
A. Aristotle’s Virtue Ethics – achieving the “Golden Mean” between extremes
B. Kant’s Duty Ethics – acting purely from moral obligation
C. Mill’s Utilitarianism – seeking the greatest benefit for society
D. Locke’s Rights Ethics – defending community rights
✅ Correct
Answer: A
She acts with
moral courage and balance — embodying Aristotle’s virtue of moderation.
Q5. (Competing
Ethical Frameworks)
A
city engineer must choose between:
- Option 1: Building a flood barrier that
protects 90% of residents but floods 10% of homes upstream.
- Option 2: Delaying the project to negotiate
full consent, risking flood damage citywide.
Which
choice aligns with utilitarian reasoning, and which with rights
ethics?
A. Option 1 = Rights Ethics; Option 2 = Utilitarianism
B. Option 1 = Utilitarianism; Option 2 = Rights Ethics
C. Option 1 = Kant’s Duty; Option 2 = Virtue Ethics
D. Option 1 = Virtue Ethics; Option 2 = Kant’s Duty
✅
Correct Answer: B
Utilitarianism values maximum total benefit (Option 1). Rights Ethics prioritizes protection of each individual’s home (Option 2).
Q6. (Justice vs. Equality vs. Benefit)
A municipality
introduces a water usage charge: wealthier households pay more so low-income
families pay less.
Some residents argue it’s unfair since “everyone uses water equally.”
Which ethical
theory most strongly justifies the city’s policy?
A. Mill’s Utilitarianism — promotes greatest benefit for greatest number
B. Kant’s Formalism — follows universal moral rule
C. Locke’s Rights Ethics — protects property ownership equally
D. Aristotle’s Virtue Ethics — seeks fairness between extremes
✅ Correct
Answer: A
Utilitarianism
supports redistributive policies if they maximize total welfare (greatest
happiness principle).
Here is a
clear explanation of each option in
the context of the water-usage policy:
A. Mill’s Utilitarianism — promotes greatest benefit for greatest number
Meaning:
Utilitarianism says a policy is ethical if it produces the greatest overall
happiness for society.
Applied
here:
Charging wealthier households more helps low-income families afford water.
This increases overall social well-being, even if some wealthy residents pay
more.
➡️ Supports the city’s
policy because it maximizes total benefit.
🟦
B.
Kant’s Formalism — follows universal moral rule
Meaning:
Kant’s ethics says actions are moral only if they follow a universal rule applied equally to everyone.
Applied
here:
Kant would likely NOT
support charging people differently based on income, because the rule is not
universal.
Everyone is not treated the same.
➡️ Does NOT justify the
city’s policy.
Kant prefers equal rules for all.
🟩
C.
Locke’s Rights Ethics — protects property ownership equally
Meaning:
Lockean ethics focuses on individual rights—especially property, liberty, and fair treatment.
Applied
here:
Locke would argue that people have a right to:
·
property (their money),
·
equal treatment under the law.
Charging different prices based on income might
violate the right to equal economic freedom.
➡️ Does NOT justify the
city’s policy.
🟨
D.
Aristotle’s Virtue Ethics — seeks fairness between extremes
Meaning:
Aristotle focuses on justice and fairness, often finding a balanced, reasonable middle path.
Applied
here:
A city charging more to those who can afford it and less to those who cannot
reflects:
·
social fairness
·
equity
·
the “just mean” between extremes of
charging everyone the same or giving free water.
➡️ Could support the policy, but not
as strongly as utilitarianism.
⭐ Which
option most strongly justifies the policy?
A.
Mill’s Utilitarianism
because it aims to increase total happiness and benefit the greatest number of
people.
Q7. (Integrity in Uncertainty)
An engineer
discovers early signs of possible failure in a design, but data is incomplete.
Reporting it could halt a crucial project unnecessarily.
She reports her concern, explaining that even if uncertain, the duty to warn
outweighs convenience.
Note: Outweighs” means is more important, more significant, or has greater influence than something else.
Which two
theories most clearly support her decision?
A. Kant’s Duty Ethics and Aristotle’s Virtue Ethics
B. Mill’s Utilitarianism and Locke’s Rights Ethics
C. Locke’s Rights Ethics and Kant’s Duty Ethics
D. Aristotle’s Virtue Ethics and Mill’s Utilitarianism
✅ Correct
Answer: A
Kant — duty to
act morally even under uncertainty; Aristotle — moral courage and professional
integrity as virtues.
Note: “The duty to warn outweighs convenience” means:
✅ Doing the right thing
(warning others of danger) is more important than doing what is easy or
comfortable.
🔍 Breakdown of the meaning
· Duty to warn = a moral or professional obligation to inform people about a danger, risk, or harm.
· Convenience = what is easier, faster, less troublesome, or more comfortable for you.
So the phrase means:
👉 Even if warning people is inconvenient, uncomfortable,
time-consuming, or creates problems,
you still must warn them because protecting safety is the higher moral
priority.
🧠 Example in engineering
An engineer discovers a potential failure in a structure.
Reporting it will cause delays, extra cost, and angry clients.
But the duty to warn outweighs the inconvenience.
So the engineer must report the danger anyway.
🌟 In short:
Safety > Convenience
Moral obligation > Personal comfort
It emphasizes professional responsibility over personal ease.
Note: “Outweigh” means to be more important, more significant, or have more influence than something else.
✅ Simple explanation
When we say:
“A outweighs B”
it means:
➡️
A is more important than B
➡️
A carries more weight in decision-making
➡️
A should be prioritized over B
🔍 Example
“Safety outweighs profit.”
= Safety is more important than making money.
“Duty to warn outweighs convenience.”
= You must warn people even if it is inconvenient.
⭐ One-sentence definition
Outweigh = to be more important than.
A developer
requests design changes that meet code but visibly reduce building safety
margin.
The engineer knows they remain legal but believes they compromise public trust.
She persuades the client to retain the original design.
Which ethical
frameworks are both evident?
A. Mill’s Utilitarianism — to satisfy the majority
B. Kant’s Duty Ethics — adherence to professional integrity
C. Aristotle’s Virtue Ethics — acting with prudence and integrity
D. Both B and C
✅ Correct
Answer: D
The decision
reflects both duty-based morality (Kant) and moral character
(Aristotle) — a hallmark of professional engineering ethics.

Section 9.3
SECTION 9.3
Section 9.3:
“Agreement and Contradiction in Ethical Theories” and
Table 9.1
(Summary of Four Key Ethical Theories)
Section 9.3
highlights that all four theories overlap in the Golden Rule — an
ethical common ground across duty, rights, utility, and virtue.
That section
emphasizes:
- How all four ethical theories can agree
(e.g., “Golden Rule,” Ten Commandments, common moral ground).
- How they may contradict each other,
especially in ethical dilemmas where each yields a different
conclusion.
- Recognition that no single theory fits all
professional engineering scenarios.
Below are eight
difficult NPPE-style MCQs — two each for:
- Mill’s Utilitarianism
- Kant’s Duty-Based Ethics
- Locke’s Rights-Based Ethics
- Aristotle’s Virtue-Based Ethics
Each question
tests the agreement and conflict dimension of Section 9.3 — realistic
and scenario-driven.
⚙️ 1. Mill’s Utilitarianism — Agreement
and Contradiction
A structural
engineer must decide whether to delay a bridge opening for additional testing.
- Delay causes traffic disruption for 50,000
commuters.
- Immediate opening risks inconvenience to a small
group if the bridge needs later repair.
From a utilitarian
viewpoint, what is the correct ethical reasoning?
A. Delay the opening; duty requires full testing.
B. Open immediately; benefits to the majority outweigh risks to the few.
C. Delay the opening; each life and safety concern must be respected equally.
D. Choose a middle path balancing virtue and duty.
✅ Correct
Answer: B
Utilitarianism
focuses on maximizing total happiness — prioritizing the greatest good for the
greatest number.
Here are the ethical theories that correspond to each option:
A. “Delay the opening; duty requires full testing.”
→ Kant’s Deontological Ethics / Categorical Imperative
Why?
· Kantian ethics says moral actions are guided by duty, not consequences.
· The engineer has a professional duty to ensure safety, follow standards, and avoid putting people at risk.
·
Even if delaying causes inconvenience, duty
requires doing what is morally right and universally
applicable:
“Engineers must not open unsafe structures.”
B. “Open immediately; benefits to the majority outweigh risks to the few.”
→ Utilitarianism (Mill)
Why?
· Utilitarianism evaluates actions based on their overall consequences.
· The morally right choice is the one that produces the greatest good for the greatest number.
· Opening the bridge prevents disruption to 50,000 commuters, which outweighs the potential inconvenience to a small group later.
C. “Delay the opening; each life and safety concern must be respected equally.”
→ Rights Ethics (Locke) or Respect for Persons
Why?
· Rights-based ethics says every person has fundamental rights (e.g., to safety, to not be put at unreasonable risk).
· The safety of even a small number of people cannot be sacrificed for convenience to the majority.
· The engineer must respect the equal moral worth of every individual.
D. “Choose a middle path balancing virtue and duty.”
→ Virtue Ethics (Aristotle)
Why?
· Virtue ethics looks for the “Golden Mean” — the balanced point between extremes.
· The engineer acts with prudence, courage, and practical wisdom.
· This approach seeks a balanced, character-guided decision, such as partial opening, temporary reinforcement, or phased testing.
In a conflict
between utilitarian and rights-based reasoning, which scenario
best illustrates the contradiction?
A. Approving a public project that benefits most but displaces a few residents
without fair compensation.
B. Refusing to lie in a report despite saving a client embarrassment.
C. Demonstrating courage and fairness in a safety review.
D. Respecting individual rights and also achieving equal welfare.
✅ Correct
Answer: A
Utilitarian
logic may justify collective gain even when it violates individual rights — a
direct ethical contradiction.
🧭 2. Kant’s Duty-Based Ethics —
Agreement and Contradiction
An
environmental engineer refuses to approve a report omitting small pollutant
data, even though omitting it would help secure funding for community cleanup.
Which principle applies?
A. Mill’s utilitarianism — greatest good for greatest number
B. Kant’s duty ethics — follow universal moral law regardless of result
C. Locke’s rights ethics — defense of property
D. Aristotle’s virtue ethics — moral moderation
✅ Correct
Answer: B
Kantian ethics
values duty and truth-telling above outcome — “Never treat people as means to
an end.”
A client
pressures an engineer to underreport project costs “to protect jobs.”
The engineer refuses, knowing it may harm workers in the short term.
Which conflict from Table 9.1 does this represent?
A. A utilitarian balance problem
B. A rights-based dispute
C. A Kantian conflict between duty and consequence
D. A virtue-based moderation dilemma
✅ Correct
Answer: C
Kant’s theory
often leads to conflict when following a universal principle (honesty) causes
harm — the “truth vs. consequence” dilemma noted in 9.3.
⚖️ 3. Locke’s Rights-Based Ethics —
Agreement and Contradiction
A city design
policy restricts homeowners from altering heritage façades. One resident argues
this violates their right to property.
Which ethical conflict is best illustrated?
A. Utilitarian vs. rights — collective heritage vs. individual freedom
B. Virtue vs. duty — fairness vs. rule-following
C. Duty vs. virtue — honesty vs. loyalty
D. Rights vs. consequence — liberty vs. happiness
✅ Correct
Answer: A
Rights ethics
focuses on inherent freedoms that may clash with utilitarian aims (public good
vs. private right).
Two engineers
disagree:
- Engineer A: “We must respect everyone’s right to
safety, even if costs rise.”
- Engineer B: “We should prioritize solutions that
help most people.”
This
disagreement reflects:
A. Conflict between Locke’s rights ethics and Mill’s utilitarianism
B. Conflict between Kant’s duty and Aristotle’s virtue
C. Agreement between virtue and utilitarian ethics
D. Agreement among all theories
✅ Correct
Answer: A
The two
positions mirror a rights-based defense (individual safety) and utilitarian
logic (collective benefit).
🏛️ 4. Aristotle’s Virtue-Based
Ethics — Agreement and Contradiction
An engineer
considers whether to publicly criticize a colleague’s mistake.

SECTION 9.4
9.4: “Example
of an Ethical Dilemma”
It describes
the case of Smith and Legault, two engineers where one (Smith) shows
substance abuse affecting safety-critical work, and the other (Legault) faces a
moral dilemma between friendship/loyalty and professional/public duty.
The section
explores how each ethical theory (Duty, Rights, Utilitarianism, Virtue)
offers a distinct interpretation — with contradictions — and concludes that fair,
well-reasoned judgment consistent with Code of Ethics is necessary.
Below are 8
difficult, NPPE-style, realistic multiple-choice questions (MCQs) crafted
from this section, each targeting applied professional reasoning and multi-theory
synthesis — exactly the style of the actual NPPE.
⚙️ NPPE-Style Ethical Dilemma Questions
(Section 9.4 — Smith & Legault Case)
Q1. (Duty vs. Friendship Conflict)
Engineer
Legault knows Smith’s software error caused a failure that could endanger plant
safety. Smith is a close friend and has a substance dependency problem. Legault
fears reporting him could destroy his career.
✅ Correct
Answer: B
Kant’s Duty
Ethics requires Legault to follow universal moral law: engineers must act
truthfully and protect the public, regardless of emotional or personal
consequences.
Q2. (Rights vs. Public Safety Conflict)
✅ Correct
Answer: B
Locke’s Rights
Ethics emphasizes the right to life, liberty, and personal privacy. However,
this conflicts with duty and utility when public safety is at stake.
✅ Correct
Answer: B
Utilitarian
ethics seeks the greatest good for the greatest number — ensuring public
safety outweighs potential harm to one individual’s career.
✅ Correct
Answer: B
Virtue ethics
stresses moderation — the “Golden Mean” between cowardice (inaction) and
recklessness (harsh reporting). Legault acts with both honesty and empathy.
✅ Correct
Answer: B
Kantian duty
(report the problem to protect public safety) directly conflicts with Rights
Ethics (respect Smith’s privacy and personal autonomy).
Q6. (Code of Ethics Alignment)
✅ Correct
Answer: B
Codes of Ethics
(across provinces) universally prioritize public safety, welfare, and
environmental protection above all personal or employer interests.
Q7. (Application of Multiple Theories)
✅ Correct
Answer: C
Legault acts
with duty (responsibility to public) and virtue (compassionate
moderation) — consistent with both Kant and Aristotle.
Q8. (Fair and Orderly Process)
✅ Correct
Answer: B
The text
emphasizes fairness, objectivity, and dignity: applying theories
systematically, balancing friendship and responsibility, and minimizing
personal harm while upholding professional integrity.
