How to spot it

Nothing in the choice is false and nothing in it is off topic. It is simply about a different part of the passage than the question is.

The mismatch takes a few shapes. The choice is about a different group of people, a different stage of a process, or a different time period. It describes what a study found when the question asked what the method could not show. It answers about the whole when the question was about one part.

The signal is that you can find support for the choice, and the support is in the wrong place. If the line you point at sits in a paragraph the question is not about, that gap is the trap.

What it looks like

Passage: A paragraph defining two soil-measurement techniques, followed by a paragraph on what one study using them found.

Question: According to the text, what limits what the sensors can show?

Wrong answer: The sensors recorded higher moisture levels in the eastern plots.

Correct answer: The sensors record surface conditions only, so deeper layers are inferred rather than measured.

The wrong answer is accurate. It is also a finding rather than a limitation, and it comes from the paragraph after the one the question is about. Both facts are in the passage; only one of them answers the question.

Why it works on people

Locating relevant text feels like finishing the job. Once you have found a line that supports a choice, the sense of having verified it is strong, and the question of whether that line is the right line rarely gets asked.

It is also the pattern that punishes skimming for keywords most directly. Searching the passage for a word from the choice will reliably find it, because the choice was built from the passage.

How to beat it

Add one step to the check you already run. After you find the line that supports a choice, look at where that line is.

If the question is about a specific paragraph, a specific study, or a specific stage, the supporting line has to come from there. Support drawn from a neighbouring paragraph is the most common form of this trap, and noticing the location takes about a second once you are looking for it.

The second habit is to name the question's target in your own words before reading the choices. Limitation. Method. Finding. Cause. Then check each choice against that word alone. A choice that describes a finding cannot answer a question about a limitation, however true the finding is.

How often it shows up

Counted in September 2026: 895 of the 19,627 questions in our practice bank contain this trap, across 1,306 separate answer choices. Some questions use it more than once.

Related patterns

• True but not asked: that one is accurate and in scope, and still fails to do the job the question set. This one is about the wrong part of the passage in the first place.
• Sounds right, never said: that one has no support anywhere in the text. This one has real support in the wrong place.
• Says the opposite: that one uses the right part of the passage and reverses it. This one reports a different part accurately.
