Question

emma was upset at not finding the cookie jar in the pantry. clearly, ______ had moved the cookie jar from its place.
a. anybody
b. somebody
c. nobody
d. everybody

Explanation:

The context states Emma can't find the cookie jar, so it's logical to conclude a specific unknown person (somebody) moved it. "Anybody" refers to any person in general, "nobody" would mean it wasn't moved, and "everybody" means all people, which don't fit the clear implication that a particular person moved the jar.

Answer:

B. somebody
