A new Johns Hopkins study that analyzed cancer incidence by birth year found that the rate of colorectal cancer, which had dropped steadily for people born between 1890 and 1950, are increasing for every generation born since 1950.

A. study that analyzed cancer incidence by birth year found that the rate of colorectal cancer, which had dropped steadily for people born between 1890 and 1950, are increasing
The rate is singular => A is wrong

B. study analyzing cancer incidence by birth year found that colorectal cancer rates, which have dropped steadily for people born between 1890 and 1950, increased
C. study, which analyzed cancer incidence by birth year, found that rates for colorectal cancer, which have dropped steadily for people born between 1890 and 1950, is increasing
D. study that analyzed cancer incidence by birth year found that colorectal cancer rates, which had dropped steadily for people born between 1890 and 1950, have been increasing
I like the first split (analyzing/which/that). Which is a non-essential modifier and is not suitable here. 'study analyzing' (B) I think has the same meaning as study that analyzed, however we need present perfect for action that started in the past and continues to this day.

E. study analyzed cancer incidence by birth year found that colorectal cancer rates, which had dropped steadily for people born between 1890 and 1950, increase
Analyzed changes the meaning + wrong tense.

As a matter of fact, both "are increasing" and " have been increasing" are incorrect. This verb occurs within another verb ("found") that occurred in the past. Therefore this verb should be "HAD been increasing".

Now to answer your question, the word " since" calls for a perfect tense. (but as stated above, here the verb should be in past perfect continuous, not in present perfect continuous as given in OA.)

Is it not because 'increase' started in the past and continue in the present so OA used 'have been increasing' ?

We need that to specify the study .
Past perfect tense is required and the rates are increasing since 1950 so we need present perfect tense .

A new Johns Hopkins study that analyzed cancer incidence by birth year found that the rate of colorectal cancer, which had dropped steadily for people born between 1890 and 1950, are increasing for every generation born since 1950.

A. study that analyzed cancer incidence by birth year found that the rate of colorectal cancer, which had dropped steadily for people born between 1890 and 1950, are increasing
Subject-verb
Rate (singular) ---> has been increasing / has increased

B. study analyzing cancer incidence by birth year found that colorectal cancer rates, which have dropped steadily for people born between 1890 and 1950, increased
Meaning:
Because the word "since" means the action is still in effect right now, therefore we need something that began in the past and persist until now ---> Present Participle [have been increased / have been increasing]

C. study, which analyzed cancer incidence by birth year, found that rates for colorectal cancer, which have dropped steadily for people born between 1890 and 1950, is increasing
Subject-verb agreement
Rates (plural) ---> have been increasing / have increased

D. study that analyzed cancer incidence by birth year found that colorectal cancer rates, which had dropped steadily for people born between 1890 and 1950, have been increasing

E. study analyzed cancer incidence by birth year found that colorectal cancer rates, which had dropped steadily for people born between 1890 and 1950, increase
Meaning error
Because the word since denotes past event persist until current event ---> Present Participle {have been increasing / have increased}

E. study analyzed cancer incidence by birth year found that colorectal cancer rates, which had dropped steadily for people born between 1890 and 1950, increase - usage of present tense is incorrect

C has idiom issue as well.

rate of - This is used for increase or decrease.
rate for - This is used for price of something.

Please correct me if my understanding is wrong.

VERITAS PREP OFFICIAL SOLUTION:

As you assess your decision points in this problem, you should recognize that the most glaring difference between answer choices is in the verbs at the end of each choice - some are singular, some are plural, and the tenses vary, as well. This should force you to look back for clues that suggest singular vs. plural and the timeline of the sentence.

In choice A, the subject of that verb "are increasing" is "the rate of colorectal cancer." The subject is singular but the verb is plural, so choice A is incorrect.

Choice B is more about verb tense, and the order is out of place. The earlier-in-time group (people born between 1890 and 1950) get the ongoing verb "have dropped" but the more recent group gets the simple past "increased," and that's paired with the just-past-the-underline signal "since" which typically suggests that the event is ongoing. This creates an illogical sequence of events, rendering choice B incorrect.

Choice C goes back to a simple subject-verb misalignment, with the plural subject "rates" and the singular verb "is increasing." Therefore choice C is incorrect.

Choice E commits another tense error. By saying that "rates increase" the sentence is suggesting that increasing is what those rates always do, and not that they have been increasing (a trend). Therefore choice E is incorrect.

Choice D, which properly pairs the plural "rates" with the plural "have been increasing," and creates a logical timeline with its verb tenses, is correct.

An important note: when you determine that you are likely dealing with a tense/timeline issue, you should be sure to look outside the underlined portion for clues that signal the proper timeline. Words like "after," "before," "during," or here "since" are easy for the testmaker to hide far from the underline where students often overlook the critical importance those words hold with regard to tense. Here "since 1950" calls for an ongoing timeline for the verb "increasing," a crucial point that can be easy for students to miss.

E. study analyzed cancer incidence by birth year found that colorectal cancer rates, which had dropped steadily for people born between 1890 and 1950, increase

when we see many tense, think about sequence of tenses. which action happen before which action.
drop must happen before the increase.
had done can show an action which happen before an action in "did" and in " have done".

had done can not show an action which happens before an action in " do"

so, only choice D is correct .
