Both Answers Are True: Separating Content From Function
Priya has finished six practice Reading sets. On factual-information items she is at 91%; on rhetoric-purpose items ('Why does the author mention X?') she is at 38%. Her error log shows the same failure each time: she picks the choice that restates content from the highlighted sentence. In her most recent set the sentence read, 'Critics of the new chronology note that the pottery shards it relies on were dated by the very stratigraphy the chronology is meant to explain.' Asked why the author mentions the shards, she chose 'to describe the evidence used to build the chronology' - a true statement about the passage - over 'to identify a weakness in the proposed chronology.' She averages 2 minutes 20 seconds on these items and finishes each section with 7 to 9 minutes unused.
1. Priya can see that both answer choices are factually true of the passage. What single question should she ask to separate them, and how does it resolve this sentence?

Ask: what job does this sentence do for the paragraph's argument - not what does it say.
The sentence is grammatically framed as an objection: 'Critics ... note that.' So the author is not neutrally describing evidence; the author is airing a challenge. That makes 'to identify a weakness' the match and 'to describe the evidence' a description of content rather than of purpose.
Two quick tests she can run in the moment:
- The deletion test. Remove the sentence. What does the paragraph lose? It loses the counterargument, not the existence of the shards (that is what the sentence is about, but the paragraph would still function without the objection being raised).
- The verb test. Purpose answers are usually verbs of argument - concede, qualify, illustrate, criticize, contrast, anticipate. 'To describe' is a verb of content. If the sentence sits inside an objection frame ('critics note,' 'some have argued,' 'it is true that'), a content-verb answer is almost always the distractor.
Her pattern is that she stops at 'is this true?' and never gets to 'is this the move?'
2. She finishes each section with 7 to 9 minutes unused while spending 2:20 on purpose items. Is this a speed problem, a comprehension problem, or something else? What change follows?
Read the worked answer
It is neither speed nor comprehension - her factual accuracy is 91%, and she has slack time. It is a decision-rule problem with a cost that hides itself: she is slow on purpose items because she is re-reading the whole paragraph looking for confirmation that a choice is true, which is the wrong test and never terminates.
Arithmetic worth doing with her: roughly 9 minutes unused across a 20-question section is about 27 seconds per item of banked time. Capping purpose items at 75 to 90 seconds frees 50 to 65 seconds each, which is exactly the currency the 2-point summary item needs. Her unused time is not a virtue; it is unspent scoring capacity.
Recommended change: a hard 90-second cap on purpose items, and a rule that any time saved is immediately spent on the summary item rather than banked.
3. Design a 15-second self-check she can run after choosing an answer on any purpose item.

The 15-second purpose check
- Verb check (5s): Does my choice name a rhetorical move ('to concede,' 'to qualify,' 'to challenge') or a content category ('to describe,' 'to state,' 'to mention')? If content, re-open the question.
- Exclusivity check (5s): Could this sentence in this paragraph be serving that motive? Or could any sentence serve it? If the motive would fit every sentence in the paragraph, it is too general to be the answer.
- Frame check (5s): Look at the words immediately before the sentence - 'Critics note,' 'Even so,' 'For example.' The frame word restricts the purpose. If my choice ignores the frame, it is wrong.
She should keep a tally for one week of how often the verb check alone flipped her answer. If it flips most of them, that is the entire fix.
