Question

okay I'm a little lost on this one :/
which choice correctly completes the sentence?
-Gently, they ______ the tiny eggs back in the nest.
*set
had setted
sat
had sat(this one looks like it could work too)

how do I know if the sentence is in present or past tense?

Answer 1

Your choice (set) is correct.

Make sure you are clear on the differences in the forms and uses of "sit" and "set."
