Question

complete the sentence with the word that best fits the overall meaning and tone. before writing a book about the history of cinema, erica searched tirelessly for a dozen ______ silent films. obscure perplexing

Explanation:

The word "obscure" means not well - known or hard to find. Since Erica "searched tirelessly", it implies that the films were not easily accessible or well - known. The word "perplexing" means confusing. There is no indication in the sentence that the films were confusing; the focus is on the difficulty of finding them.

Answer:
