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' ?

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


The answer is D


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}

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 agreement issue - rate is singular
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 - usage of verb tense - increase is incorrect as the action is still occurring ; usage of which have is incorrect
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 bern agreement , rates is plural ; usage of which have is incorrect
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 - usage of present tense is incorrect

Answer D
