Question

we hardly __________see him go to church

Answer 1

Answer -

We hardly ever see him go to church.

Reason -

The reason why the answer to that sentence is "ever" is because it says "we hardly" and when it says that then "ever" is most likely to be the answer. You didn't give us answer choices so I'm giving the answer of what I think it is and using my knowledge.

Hope this helps.
