Which answer best describes the verb tenses in the sentence?

by the time we got to austin, the puppy falls asleep in the back of the van.

a.
the verb tenses are consistent.

b.
the verb tenses shift.

The correct answer is B. The verb tenses shift.

This is because we have the verb "got" which is past simple, and the verb "falls" which is present simple tense. Consistency would mean that they are both either past simple or present simple.
