Question

Which sentence correctly uses the past perfect tense?

Carl has packed three suitcases for his trip.

Carl bought a ticket three weeks in advance.

Carl had asked his mother’s permission before he left town.

Carl will have lost his map by the end of the trip.

Answer 1

C. Carl had asked his mothers permission before he left town, this is the correct one because the keyword is "Had" and "before"

Answer 2

Carl had asked his mother’s permission before he left town.

Step-by-step explanation:

Past Perfect is used to describe something that happened before another thing that has also already happened.

In this case, before leaving town, Carl asked his mother for her permission. First he got permission from his mother, then he left town. Both things happened in the past, but the permission asking happened first.
