LNAT counterargument question practice

Test the conclusion by finding the choice that exposes why its evidence may not justify the result.

Weekend street surveyWritten by Margin

Westbridge Council surveyed 500 visitors during its weekend street festival. Sixty-eight per cent preferred the high street without cars. The council says this proves the road should close permanently. The festival included food stalls and live music, and the survey did not record whether respondents were local residents, traders, delivery drivers or weekday commuters.

Which choice is the strongest counterargument to the council’s conclusion?

The festival survey may not represent people affected by a permanent weekday closure
Many other councils have created pedestrian zones
Cars should never be banned from town centres
Most festival respondents preferred the road without cars

Original practice exercise; counterargument questions are not an official LNAT category.

Which choice tests the conclusion?

Choose A. The council moves from festival visitors to everyone affected by a permanent weekday closure. A targets that gap.

Margin answer audit
Choice	Verdict	Why
A	Strongest	The sample may exclude traders, delivery drivers and weekday users affected by the permanent policy.
B	Irrelevant	Other councils’ choices do not show whether Westbridge’s survey supports its conclusion.
C	Too broad	The passage concerns this permanent closure; it gives no basis for rejecting every car ban.
D	Restates	This repeats the council’s evidence instead of challenging the move from a festival to a permanent policy.

What are LNAT counterargument questions?

Margin uses “counterargument questions” as a practice label for testing a passage’s conclusion. Official LNAT preparation material names forming counterarguments as a useful reading skill, not a standalone question category.

The current format page describes 42 multiple-choice questions based on 12 argumentative passages. Margin uses this label only for one reading skill.

How do you find the strongest counterargument?

Identify the conclusion and its evidence, then choose the option that most directly weakens the link between them. Ignore choices that merely change the subject.

The official preparation page asks how you would frame a counterargument. Here, the survey sample is the narrowest point to test.

Must a counterargument disprove the conclusion?

No. A strong counterargument can show that the stated evidence is too narrow to justify the conclusion, even when the conclusion could still be true.

The official preparation guide names forming counterarguments as useful for legal study and includes it in a reading checklist.

Margin is independent LNAT practice. LNAT did not supply this exercise, and it does not predict a Section A score.

Objections you have not met before

The strongest objection sits somewhere different in every argument, which is why one worked example does not settle the skill. 10 of the 83 questions on the practice page are free. Founder access is £25 for the other 73, each with the passage sentence your answer turned on.
