Since published is in the past..ie., she published a report on something that had happened before..so, past perfect needs to be used here..it is correctly used only in option A...the second part of (B) after the semi-colon talks about ..if they are born, which is awkward.

I think A would be correct choice.

According to a study published by Dr. Myrna Weissman, only one percent of Americans born before 1905 had suffered major depression by the age of seventy-five; of those born since 1955, six percent had become depressed by age twenty-four.
(A) only one percent of Americans born before 1905 had suffered major depression by the age of seventy-five; of those born since 1955, six percent had become depressed by age twenty-four [seems correct syntactically and meaning-wise]
(B) only one percent of Americans born before 1905 suffer major depression by the age of seventy-five; if they are born since 1955, six percent become depressed by age twenty-four [incorrect usage of the word suffer; should be suffered. Similarly for become]
(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 [have suffered should be had suffered; since 1955 did by..]
[only one percent of them--unnecessary usage of them. omitting it makes the meaning clear as well]
(D) major depression is suffered by the age of seventy-five by only one percent of Americans born before 1905, and by age twenty-four by the six percent born since 1955 [no matching between only one percent and by the six percent;Incorrect sentence construction]
(E) Americans born before 1905 suffer major depression by the age of seventy-five only one percent of the time, but six percent of those born since 1955 did so by age twenty-four [suffer ..did so...No matching of tenses...also the meaning becomes ambiguous..by the age of seventy-five only one percent of the time..are we referring to a period/ passage/ quantity of time?]
Plz clarify between A, B and E....
E seems to be appropriate....????..
In A had is required or not????

In this question, we are trying to show contrast between people who are born before 1905 and since 1955. The usage of "if" is not very apt, also u can observe that a present tense is usage "Americans born before 1905 suffer major depression" and thus the choice can be eliminated.

I am studying verb form/tense tab
I see that the actions is in the past but B,C,D,E, use verb in present time. so, B,C,D,E are wrong.

is my thinking correct?

"By the end", "by the age" demand the use of past perfect. But "since" used in context of time demands present perfect.

In the original sentence since and by the age is used together. Is it correct to use past perfect?
Experts??

In "those born since 1955", "since" means "after". You need to use the past perfect to imply that the Americans became depressed "before" they turned (simple past) 24.

Read the sentence with present perfect:
Of those born after 1955, six percent have become depressed by age 24.

The present perfect is used for actions occurring in this window: past--present. But the Americans did not turn 24 today. You cannot combine the present perfect with markers of the past such as "last week" or "by some (past moment)".

Two events and both are completed in the past. So we need had with the event that happened before ie even 1.

1. People born before 1905 suffered by the age 75 and those born after 1955 depressed by the age 24.

2. Study published

Study published - only one percent of Americans born before 1905 had suffered major
depression by the age of seventy-five; of those born since 1955, six percent had become depressed by age twenty-four

According to a study published by Dr. Myrna Weissman, only one percent of Americans born before 1905 had suffered major depression by the age of seventy-five; of those born since 1955, six percent had become depressed by age twenty-four.

(A) only one percent of Americans born before 1905 had suffered major depression by the age of seventy-five; of those born since 1955, six percent had become depressed by age twenty-four

(B) only one percent of Americans born before 1905 suffer major depression by the age of seventy-five; if they are born since 1955, six percent become depressed by age twenty-four

(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

(D) major depression is suffered by the age of seventy-five by only one percent of Americans born before 1905, and by age twenty-four by the six percent born since 1955

(E) Americans born before 1905 suffer major depression by the age of seventy-five only one percent of the time, but six percent of those born since 1955 did so by age twenty-four

This is a finding of a study that specifically deals with the phenomenon of mental depression in different age groups, one in the deep past and another in the near past. However, both of them occurred and ended in the past. In such a context, we are not supposed to assume that they are both universal happenings or daily chores to describe them either in the present tense or the present perfect. On this score alone, we can dispense with B, C, D, and E.
However, is it correct to use past perfect for both events as in A? Obviously, we are tempted to say that the youngsters' depression is the later one and we should, therefore, use a simple past. Unfortunately not so. Add 75 to 1905 and it is 1980. Add 24 to 1955 and it is 1979, around the same time as 1980. In this case, we could use simple past for both the events provided there is no third event that is the last in the passage.
Nevertheless, the passage says that there is a third event that occurred later i.e., the researcher's publication that was distinctly later than the prior two events. Hence, we can use past perfect for both those earlier events.
