Q: Based on recent box office receipts, the public's appetite for documentary films, like nonfiction books, seems to be on the rise.
A. like nonfiction books
B. as nonfiction books
C. as its interest in nonfiction books
D. like their interest in nonfiction books
E. like its interest in nonfiction books
Based on the Like Vs As rule, answer option E is the best fit i.e
"Based on recent box office receipts, the public's appetite for documentary films, like its interest in nonfiction books , seems to be on the rise."
However, does this sentence not violate the possessive antecedent princpal? What does "its" refer to here?
