Question

fix the verb that doesnt match the tense of the verb in bold.
i started a movie, but i fall
fast asleep after just five or ten
minutes.

Explanation:

The bold verb "started" is in the simple past tense. To maintain tense consistency, the verb "fall" should also be in the simple past tense. The past tense of "fall" is "fell".

Answer:

Change "fall" to "fell". The corrected sentence is: "I started a movie, but I fell fast asleep after just five or ten minutes."
