Question

insert the correct adverb!
i caught up on my tv show ______ i was knitting.
choose 1 answer:
a why
b when
c who

Explanation:

To solve this, we analyze the context. The sentence is about two actions (catching up on a TV show and knitting) happening at the same time. "Why" is used for reasons, "who" is for people, but "when" is used to indicate a time or while an action is happening. So "when" fits here as it shows the time during which both actions occurred.

Answer:

B. when
