Question

Select the correct verb form for the sentence. i would be able to _____ that tree if it weren't for my bad shoulder. climbs climb climbed climbing

Answer 1

the correct answer is ''climb''

Answer 2

I would be able to climb that tree if it weren't for my bad shoulder.

We need to use climb in this sentence. Because we know that to goes before the verb, we know we have to use the infinitive (to climb). It does not make any sense to say "to climbs," "to climbed," or "to climbing."
