138.Causation links:
A Error and cost
B Breach and harm
C Contract and fee
D Policy and law
Answer: B
Correct Answer: B — Breach and harm
✅ Why B
is Correct
In
negligence law, causation establishes the
connection between:
·
A
breach
of duty
(failure to meet the standard of care), and
·
The
harm
or damage
suffered.
Courts
ask whether the professional’s breach actually caused the harm.
Two
common legal tests used:
1.
“But-for test”
But
for the engineer’s breach, would the harm have occurred?
2.
Proximate cause / foreseeability
The harm must be a reasonably foreseeable consequence of the breach.
This
framework is commonly applied in professional liability cases involving
engineers regulated by bodies such as Professional Engineers Ontario.
High-yield
NPPE phrase:
Causation
connects the breach of duty to the resulting damage.
❌ Why
the Other Options Are Incorrect
A) Error and cost
An error may increase cost, but causation in negligence law concerns linking breach to harm, not simply financial
consequences.
C) Contract and fee
Contracts govern payment obligations; they are unrelated to the legal concept
of causation in negligence.
D) Policy and law
Policy and law relate to regulation and governance, not the cause-and-effect
relationship required to establish liability.
🎯 NPPE Memory Shortcut (Very Useful)
To
prove professional
negligence,
four elements are usually required:
1.
Duty of care
2.
Breach of standard of care
3.
Causation
4.
Damages
Think
of it as: Duty
→ Breach → Causation → Damage
Example 1 Here is a very typical NPPE-style
scenario question that tests the four elements of negligence: duty, breach,
causation, and damages.
NPPE Scenario Question
An
engineer designs a retaining wall for a residential development.
The engineer fails to properly check the soil report and underestimates the
lateral earth pressure. Two years later, the wall collapses and damages several
parked vehicles.
Which
element of negligence connects the engineer’s failure to review the soil report
with the resulting property damage?
A.
Duty of care
B. Breach of standard of care
C. Causation
D. Damages
Correct Answer: ✅ C — Causation
Explanation
To prove negligence, all four elements must exist.
1️ Duty of Care
The engineer had a professional duty to design the retaining wall
safely.
2️ Breach of Standard of Care
Failing to properly review the soil report is a departure
from accepted engineering practice.
3️ Causation ✅
The collapse occurred because the soil pressure was
underestimated.
This links the breach (design error) to the harm (wall
collapse and vehicle damage).
4️ Damages
The damaged vehicles represent actual loss
or harm.
Why the Other Options Are Wrong
A — Duty of care
This establishes the professional responsibility, but it does not connect the
breach to the harm.
B — Breach of standard of care
This identifies the mistake, but it does not prove the mistake caused the
damage.
D — Damages
Damages show that harm occurred, but they do not establish what
caused the harm.
NPPE Exam Memory Trick:
Remember the sequence:
Duty → Breach → Causation → Damages
Or simply:
DBCD (Duty–Breach–Causation–Damage)
A lawsuit fails if any one of these four elements is missing.
Here
are 3
very common NPPE negligence scenario traps. These are designed to
confuse candidates when questions test duty, breach, causation, and damages.
1️ The Breach
vs Causation Trap (Most Common)
Scenario Example
An engineer incorrectly sizes a stormwater pipe. Later, flooding
occurs during a major storm.
Q. Which element
must be proven to link the design error to the flooding?
A. Duty of care
B. Breach of standard of care
C. Causation
D. Professional reputation
The Trap: Students often choose B (breach) because they see the design error.
But the question asks for the element that links the
error to the damage.
Correct Answer
✅ C — Causation
Key idea:
·
Breach = mistake
·
Causation = mistake caused the
damage
NPPE phrase:
Causation connects the breach to the harm.
2️ The Damage
Without Liability Trap
Scenario Example: A bridge designed by an engineer collapses during
an earthquake far beyond the design standard.
Question: Which element of negligence may be missing?
A. Duty
B. Breach
C. Causation
D. Damages
The Trap
Many candidates see the collapse and immediately assume negligence.
But negligence requires all four elements.
Correct Answer: ✅ B — Breach
If the engineer followed all standards and codes, there may be no breach of
the standard of care, even though damage occurred.
Key idea: Damage alone does not prove negligence.
3️ The Duty
vs Breach Confusion Trap
Scenario Example
An engineer seals drawings prepared by an unqualified person without
reviewing them.
Question:Which element of negligence is most clearly violated?
A. Duty of care
B. Breach of standard of care
C. Causation
D. Damages
The Trap
Students choose A (duty) because they
know engineers have responsibility.
But the duty already exists automatically when
providing professional services.
Correct Answer
✅ B — Breach of
standard of care
The engineer failed to meet professional
practice standards by not reviewing the work.

✅ NPPE exam insight:
Most negligence questions are testing whether you can distinguish between breach and causation.
TIPS: The single fastest way to answer negligence questions in
under 10 seconds
When you see a negligence question, immediately check for the four elements:
Duty → Breach → Causation → Damages
Ask these four quick questions:
1️ Did the
engineer have responsibility? → Duty
2️ Did the
engineer do something wrong? → Breach
3️ Did that
mistake cause the harm? → Causation
4️ Did someone
suffer loss or damage? → Damages

Example (Solve in 5 Seconds)
An engineer fails to check a structural calculation. The beam later
fails and damages property.
Question: Which element connects the design error to the property
damage?
Steps:
1.

Breach causes → causation.
Harm occurs → damages."
NPPE Exam Insight (Very Important)
Most negligence questions do NOT test the full concept.
They usually test only one element, especially:
·
Causation
·
Breach
These two are the most commonly examined.
Here
are 5
very common NPPE negligence questions. The wording changes from exam to exam,
but the core
concepts repeat frequently.
1️ The Four
Elements of Negligence
Q. Which of the following is NOT
required to prove professional negligence?
A. Duty of care
B. Breach of standard of care
C. Causation
D. Criminal intent
✅ Correct
Answer: D — Criminal intent
Why Negligence requires:
·
Duty
·
Breach
·
Causation
·
Damages
Criminal intent is not required.
NPPE takeaway: Negligence is civil liability,
not criminal wrongdoing.
2️ The Standard
of Care Question
Q. The professional standard
of care is judged based on:
A. Perfect performance
B. What a reasonable professional would do in similar circumstances
C. The client’s expectations
D. The lowest cost solution
✅ Correct
Answer: B
Why Courts evaluate conduct based on the reasonable engineer standard.
Key phrase: Reasonable and prudent professional under similar
circumstances.
3️The Causation
Question
Q. Causation determines whether:
A. The engineer had a duty
B. The engineer was licensed
C. The breach caused the harm
D. The client approved the design
✅ Correct
Answer: C
Why Causation links the breach
of duty to the damage
suffered.
Legal test often used:
But-for test — would the damage have
occurred but for the engineer’s actions?
4️The Foreseeability
Question
Q. Foreseeability refers to:
A. Past incidents only
B. Predicting risks based on reasonable professional judgment
C. Client concerns
D. Insurance assessment
✅ Correct
Answer: B
Why Foreseeability asks whether a reasonable engineer could anticipate the harm.
This determines whether the engineer had a duty to
prevent the risk.
5️The Damage Alone Trap
Q. A structure fails due to an extreme natural disaster well beyond
design standards. Which element of negligence may be missing?
A. Duty
B. Breach
C. Causation
D. Damages
✅ Correct
Answer: B — Breach
Why
The engineer may have followed all codes and standards.
If the engineer met the standard of care, there is no breach, even if
damage occurred.
Key NPPE principle:
Harm alone does not prove negligence.
Final NPPE Negligence Summary (High-Yield)
To
prove negligence:
1️ Duty of care
2️ Breach of standard of care
3️ Causation
4️ Damages
