In 1989 Dr. Weissman and her colleagues published results from five cities in the United States showing an increasing risk of depression at some point in life for younger Americans. For example, of those Americans born before 1905, only 1 percent had suffered a major depression by age 75; of those born since 1955, 6 percent had become depressed by age 24. That trend was corroborated earlier this year by a six-year study of 956 American men and women which found that those under 40 were three times more likely to become severely depressed than were older groups. The current findings suggest this trend is worldwide.

41. 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
Two concepts. 1. Use of semi colon 2. Use of past perfect tense.
Semi colon - Used with two independent clause which should be related to each other.
Past Perfect tense - Started with one point of time in past and should be continuous till another time of past, or its effect should remain till that time.
First let's analyze all options except A.
(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
1. First problem is with tense.
"Suffer" represent present tense so can not refer past.
This has to be in perfect tense because those 1% of americand were still suffering after age of seventy-five
2. Second problem is with Pronoun.
Here "if they are born" referring to the same people "one percent of Americans" but as mentioned later in sentence that now the number is 6% and these people or this group is different from "one percent of Americans".
(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
1. GMAT perfer they in place of them.
2. "Have suffered" means those people are still suffering
(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
1. Here first cluase is passive construction ( by x); Suffer is intrasitive verb so we can not have passive sentence with it, or in another words, Major depression can not be suffered by anything.
2. "by age twenty-four by the six percent born since 1955" is not correct construction and meaningless.
(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.
1)If we remove "the age of seventy-five" then remaining sentence is -Americans born before 1905 suffer major depression by only one percent of the time " , okay they only suffer 1% time 99% percent they are out of depression. Wrong meaning.
2)Suffer is in the present tense.
(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.
Let's assume Americans born before 1905 were = 6000
those born since 1955= 80000
Then sentense is
only one percent of 6000 had suffered major depression by the age of seventy-five; of 8000, six percent had become depressed by age twenty-four.
1. Use of perfect tense because major depression or its effect is continious.
2. Both of these sentences are independent and related as we are talking about americans.
I hope my explanation will help.

(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.
