Question

In 1960, American scientists raise a serious concern.

A.raising
B.raised
C.have raised
D.no change necessary

The word underlined is raise and they want you to identify the correct form of it. I think it would be B. raised

Answer 1

raised...past tense remember

Answer 2

Are you saying it would be C then? Because I thought I was trying to use it in past tense form since they are talking about 1960?? Or were you saying I was correct

Answer 3

No, I don't think what dude means. Your answer B is correct.

Answer 4

it probably would be B.."in 1960, american scientists raiseda serious concern"

vs

"in 1960, american scientists have raised a serious concern"
