At a certain library, audio books on CDs can be checked out for three

IMO the answer shall be 'A'. The premise for increasing the duration of keeping the audio books is rightly brought out in 'A' i.e comparing it with printed books. Additionally, comparing audio books with music CDs would be wrong, which is also brought out in 'A'.
Option 'C' says the opposite. According to option 'C', the duration for both audio and music CDs shall be increased, which is not the case.

A appears to be the most logical one, people consume audiobooks like physical books and thus need to borrow them for a longer time span to be able to get the maximum utility.

Have not seen this question type before though, or maybe I was just oblivious to it...

tricky one.
C says " People who checked out audio books, like people who checked out recorded music, often kept the library's materials longer than the authorized ten-day period", then why didn't director change the policy for both music CD and audiobooks on CD? It seems illogical to only extend the check-out time for audiobooks on CD. so C is incorrect.
Am I right? thank you guys.

At a certain library, audio books on CDs can be checked out for three weeks at a time while music CDs can be checked out for only ten days at a time. The library initially categorized audio books in such a way that they could only be checked out for ten days at a time, but the library director recently changed the library's policies so that audio books could be checked out for three weeks at a time.

Pre-think:
library items - audio books - 3 weeks, music CDs - 10 days

Initially time for all was same but later director changed the time for audio books to 3 weeks, as in some how audio books need more time then music cds.

As confusion is between A and C.

A. In the ways that people use them, audio books are more similar to printed books than they are to recorded music. --- well this choice creates a difference between both type of items. and this is why director takes a stand to keep different time for both items.

C. People who checked out audio books, like people who checked out recorded music, often kept the library's materials longer than the authorized ten-day period. ------ problem with this choice is this part "like people who checked out recorded music", if so then why no increase the time for recorded music as well, why just increase the time for only 1 thing.

Gegeyan - let me know about your doubts.

Which of the following is a premise upon which the library director's decision could have been based?

"Initially: audio book - 10 days & music CD - 10 days (somehow audio book & music CD were thought to be similar that why they were allowed to be checked out for 10 days for both)
Changed to: audio book - 3 weeks & music CD - 10 days (somehow audio book & music CD are thought to be dissimilar/different that why they are allowed to be checked out for 3 weeks &10 days respectively --> any thought related to this will be directory thinking/premise/support)

A. In the ways that people use them, audio books are more similar to printed books than they are to recorded music. --> correct
B. audio books cost, on average, more than twice as much as the equivalent hardcover version of the printed book. --> cost is not the point discussed here. No comparison related to audio book & music CD
C. People who checked out audio books, like people who checked out recorded music, often kept the library's materials longer than the authorized ten-day period. --> weaken: showing similarity between audio book & music CD. If both audio book is checked out by the people like those who checked out music CD, then why both are not allowed to be checked out for 3 weeks?
D. Because most people can listen to a story for a longer period than they can read the same story, most people finish audio books faster than they could finish the printed version. --> irrelevant: No comparison related to audio book & music CD
E. To get the most out of a book, people should read the original edition of the printed text instead of a condensed audio book version. --> irrelevant: No comparison related to audio book & music CD

Could anyone specify whether questions such as these could be expected on the GMAT as well?

I did not come across something similar in my prep material so far.

Like many others, I was confused between A and C but realised the latter is a weakener, if anything. A on the other hand makes sense, because if audio books are more like printed books than recorded music, which can be consumed in a shorter time frame as compared to a book, then longer check out time is more logical.

C seems to weaken the argument because the library stands to lose late fine revenue if it kills the proverbial cash cow.

Would be happy to get your feedback.
