Question

read the source of the allusion.
lewis carrolls alices adventures in wonderland tells the story of a young girl who follows a white rabbit down a rabbit hole and finds herself in a series of adventures in a surreal world.
what is the meaning of the allusion in the sentence below?
kennys research on nineteenth - century philosophers led him down the rabbit hole.
on a strange or difficult exploration
into focused study
in search of acclaim or praise

Explanation:

In "Alice’s Adventures in Wonderland", going down the rabbit hole leads to a surreal, strange, and complex adventure. In the sentence about Kenny's research, "down the rabbit hole" alludes to his research being a strange or difficult exploration, as philosophical research (especially on 19th - century philosophers) can be complex and lead one into an in - depth, perhaps bewildering exploration. The option "into focused study" is too simplistic as "rabbit hole" implies more than just focus, and "in search of acclaim or praise" has no relation to the allusion's meaning.

Answer:

on a strange or difficult exploration
