IMO B.

C- of Americans born before 1905, only one percent of them have suffered major depression by age seventy-five, but six percent of those born since 1955 do by the age of twenty-four

Here, "six percent of those" means 'six percent of Americans born before 1905'. How can people who are born since 1955 be considered as those born before 1905? looks confusing

anything wrong with A? IMO it is OK.
B - conditional statement and Tense is not proper.
C - "of them" is redundant. Tense.
D- tense and passive, this is IMO closest one.
E- for some reason two verbs don't agree in tense.

what is wrong with D.

it cannot be passive coz, Depression is subject, the subjunctive clause "According to a study published by Dr. Myrna Weissman" is clearly referring to Depression.

Also the other closer OA is A - which has pronoun "those" referring to 1% of american ppl, rather than american ppl.

E, C has similar problem as A.

B is ackward with if construction

OA is A.

The problem with D is:

"by age twenty-four by the six percent born since 1955"

This makes it sound like there were only 6%, it should say 6% of...

At least that's the one thing I found wrong.

can someone explain the passive voice to me? What is considered passive? I've seen numerous postings about the GMAT not liking a passive voice, not sure what that means.
