Complete the sentence with the correct form of the verb in brackets: "After the long hike we ____ (feel) hungrier than ever."

Explication

The hike is over, so the sentence reports a finished past state and takes the past simple, which for feel is felt. This verb keeps only two written shapes, so felt is also what follows have: we have felt this before uses the same word without any extra ending. The regular feeled does not exist, and leaving the base form would strip the sentence of tense.
