Passive vs. active voice

[Castro]

Hello:

I got a question:

"The result is supported by recent psychological research, which revals that after 20 mins spent reading fashion magazines, most women ___feelings of insecurity about their bodies."
A.have been reported
B.was reported
C.reported
D.reporting

I am not sure which of the answer should be filled in the box.
The sentence "most women......their bodies" is a adj.clause or a phrase?
Please help me to find out the answer.Thank you.

Hello, Castro!

Let?s try it!

I think the correct answer is C-reported

As for your second question, I haven?t got
a clue but, from my point of view, I think
the second comma is not necessary. Actually, I
think it?s wrong. Therefore, I see the sentence
"which... most women..." as a subordinate
relative clause.

The teacher will help us, anyway :P

.
The result is supported by recent psychological research -- Main clause of sentence

, which reveals that after 20 mins spent reading fashion magazines,most women reported feelings of insecurity about their bodies -- nonrestrictive dependent clause modifying research and requiring the comma preceding it

that after 20 mins spent reading fashion magazines, most women reported feelings of insecurity about their bodies -- dependent restrictive clause acting as the object of reveals

after 20 mins spent reading fashion magazines -- dependent sub-clause as adverbial of the following:

most women reported feelings of insecurity about their bodies -- independent subclause of that-clause.

Is that clear?
