Question

Which verb form correctly completes the sentence? Earlier, when Bruce arrived, I noticed that he _____ his shirt. A. torn B. had torn C. tear D. had tore

Answer 1

A) torn
Look at clues if there are any -ed or -s. Since 'arrived' had a "-d" and 'noticed' did too, torn will sound better when put into words.
The sentence above is in past tense so I think it would be torn

Answer 2

The correct answer is B-had torn (Past Perfect)
Because there are 2 actions in the past and the action of tearing occurred before the action of noticing.So, the 1st action is Past Perfect (had torn)and the 2nd action is S.Past (noticed)
