Question

what is the source of the allusion in the sentence below?
leo tolstoy’s war and peace is a behemoth of a book.

the bible
a poem
greek mythology

Explanation:

The word "behemoth" in the context of the allusion here comes from the Bible (specifically the Book of Job, where Behemoth is a large creature described). The other options: a poem doesn't relate to the origin of "behemoth" in this allusion, and Greek mythology has different mythological creatures, not Behemoth as used here. So the source is the Bible.

Answer:

the Bible
