Research, then pre-phrase
The question asks about adoption. Return to the last sentence and keep both parts of the pre-phrase:
The science was in hand before the standard became law, and what held it up was money.
Critical Analysis and Reasoning Skills
It's not your
ability.
It's your
blind spots.
You get it down to two and lose the point anyway. Or you read every sentence with care and still run out of time. Either way, the explanation afterward usually makes sense. But knowing why you were wrong yesterday and noticing that you’re about to be wrong right now are two different skills.
Reading an inference choice
You don’t pick answers,
you pick them apart.
On inference questions. On retrieval, research the requested information and select the choice that answers the question.
For Psych/Soc, you spot biases in others. On CARS, you have to catch your own.

The passage
But the foremost obstacle they faced was never acoustic. Instrument makers had built inventories to local pitches, and a national standard would render that stock unsellable overnight.
Although the physicists supplied the decisive measurements, it was the compensation schemes negotiated with the trade, and not the measurements, that moved the standard from proposal to law.
Read the full paragraph
Before the nineteenth century, no two orchestras in Europe tuned alike. A visiting soloist arriving in Vienna found the ensemble pitched nearly a semitone above the one she had left in Paris, and singers complained, with some justice, that rising pitch was shortening careers. The reformers who eventually settled the question are usually described as having solved a technical problem, and the description is not wrong so far as it goes. But the foremost obstacle they faced was never acoustic. Instrument makers had built inventories to local pitches, and a national standard would render that stock unsellable overnight. Although the physicists supplied the decisive measurements, it was the compensation schemes negotiated with the trade, and not the measurements, that moved the standard from proposal to law.
The question stem
The passage suggests which of the following about the adoption of a standard pitch?
How the question reaches this comparison
First read-through · The mallet
A claims the measurements were less accurate than the reformers believed. Your pre-phrase says the science was already in hand: it denies A. You can fault A in one line without returning to the paragraph. B, C, and D stay. Three choices survive.
Refresh, then use the scalpel
Recall the complete pre-phrase before examining the survivors. D says singers were the group most harmed. The paragraph never ranks how much each group suffered, so D goes.
Now inspect B and C
Familiar words do not settle the question. Test the claims against what the passage establishes. B has two unsupported claims; C restates the relationship the paragraph shows.
At this point in the second read-through, B and C remain. Refresh the pre-phrase: the science was ready; money held up adoption.
01 Two choices remain02 Claims inspected
Instrument makers opposed standardization primarily to protect their existing inventories.
B survived the first read-through. You could not fault it in one line without checking the paragraph.
The passage“inventories”
A technical solution can be available for some time before the conditions for its adoption exist.
C also survived. Its unfamiliar wording is no reason to cross it out; test what it claims.
The fix existed before anyone could put it in place.
C is the answer.
The science
but“the physicists supplied
the decisive measurements”
Adoption
“the compensation schemes
negotiated with the trade”
C restates this relationship. B adds claims the paragraph does not establish.
BThe tempting one
“opposed”
First, the paragraph never shows the instrument makers opposing anything.
“primarily”
Second, primarily ranks motives. The paragraph gives the makers one reason and never weighs it against any other, so nothing in it supports ranking that one first.

It used the passage’s words, so I trusted it.
The moment to catch it
The flicker of recognition at a phrase. If an inference choice feels right because you have seen its words before, ask what those words claim in this sentence.
How the approach prevents it
Look past the words to the claim.
Whose claim is it? How are its parts joined? How far does it go? Familiar wording calls for a closer check, never automatic elimination. On retrieval, passage wording is expected.
