Question

fix the verb that doesnt match the tense of the verb in bold.
david catches a buckeye butterfly
in his net and then let it go.

Explanation:

The bold verb "catches" is in the simple present tense (third - person singular). The verb "let" in the sentence "and then let it go" does not match the tense. Since the subject "David" is third - person singular and the first verb is in simple present, the second verb should also be in simple present (third - person singular) form. The third - person singular form of "let" is "lets".

Answer:

Change "let" to "lets". The corrected sentence is: David catches a buckeye butterfly in his net and then lets it go.
