Stimulus Summary
1712 - All books published need approval by a censor
Censor #1 - 50% not approved (50% approved)
Censor #2 - 25% not approved (75% approved)
The same number of books were approved by both censors
Answer Anticipation
This Must be True question deals with percentages and amounts, but we’re not looking for a flaw. Instead, we need to make an inference based on these numbers.
We learn that the two censors approved the same number of books, but one approved a higher percentage than the other. Since the first censor approved a lower percentage of books she reviewed, but it was the same number of books, she must have looked at more books!
If you’re having trouble seeing that, let’s put some quick numbers into play. Let’s say the second censor looked at 100 books. He approved 75 of them. We know that the first censor also approved 75 books, but that was only 50% of the books she reviewed. As such, she must have reviewed 150 books (since 75 is 50% of 150) - that’s more than the 100 the second censor looked at.
Let’s find an answer stating that the first censor reviewed more books than the second.
Answer choices
-
AMore books critical of Remaining source text redacted.
Why choice A is not credited
There’s no discussion of the rate of critical books being published before the censorship law kicked in, so this answer is out of scope. -
BThe first censor and Remaining source text redacted.
Why choice B is not credited
They approved the same number of transcripts, but they rejected a different percentage. As such, they couldn’t have rejected the same number. (Using the numbers above, the first censor rejected 75, and the second rejected 25.) -
CMore book manuscripts were Remaining source text redacted.
Why choice C matches the stem
This answer matches our anticipation. If the second censor approved a higher percentage of books but the same amount, then the first censor must have reviewed more books. -
DThe second censor allowed Remaining source text redacted.
Why choice D is not credited
While possible, there’s no indication that the criteria or judgment of the two censors was different, so this answer is not something that must be true. -
EThe number of writers Remaining source text redacted.
Why choice E is not credited
We learn information about the books submitted, not the writers. Each author could have submitted only one book; or a handful of authors could have written many books. There’s no way to know.
