GMATNinjaWhy is Option A correct.
Here the comparison is between how the 'Early medieval libraries' act v/s how do the modern libraries act.
So shouldn't this comparison be explicitly indicated by 'as' rather than 'like'
Hi
Let me try to answer your query.
"Like" is typically used to indicate similarity and is used preceding nouns. For eg:
John and Stuart, like their father Benjamin, are left handed.Here, we communicate the idea that John and Stuart are
similar to their father Benjamin in the fact that they are right handed.
"As", on the other hand, is used to indicate "the same". It is typically used before a clause. However, "as" can also be used to indicate roles or functions, in which case it can be used before a noun as well. For eg:
John works in an auto firm, as does Stuart. Here, we intend to communicate that John and Stuart
are the same in the specific fact that both work for auto firms.
As your teacher, I must tell you about your weaknesses. Here, we communicate my
role of a teacher and hence the use of "as" is justified.
Now, coming to the question under consideration, the idea being communicated clearly is that early monasteries are
similar to modern libraries in that they "served as repositories for texts". Hence, "like" is the correct usage.
Hope this helps.
