Fill in the blanks using correct tense forms : Joe’s cat _____ into the river yesterday. A. fell B. was falling C. have fallen D. is falling

The correct answer is A. fell.

The sentence is in the past tense, so we need to use a past tense verb. Option B, was falling, is in the past progressive tense, which is used to describe an action that was happening at a specific time in the past. Option C, have fallen, is in the present perfect tense, which is used to describe an action that happened at an unspecified time in the past or that has happened repeatedly in the past. Option D, is falling, is in the present tense, which is used to describe an action that is happening now.

In this case, we know that Joe’s cat fell into the river yesterday, so we need to use a past tense verb. Option A, fell, is the only past tense verb that is grammatically correct.
