Neither result of the two experiments involving Alzheimer's patients were what the researchers have expected.

(A) Neither result of the two experiments involving Alzheimer's patients were what the researchers have expected.
(B) Of the two experiments involving Alzheimer's patients, neither result was expected by the researchers.
(C) Neither of the two experiments involving Alzheimer's patients result in what the researchers expected.
(D) Neither of the two experiments involving Alzheimer's patients resulted in what the researchers had expected.
(E) What the researchers have expected was the result of neither of the two experiments involving Alzheimer's patients.

A. Subject verb error. Were should be was. Verb tense error, the entire sentence is in past, have expected is incorrect.
B. The second part should be- Neither of the result was what the researchers had expected.
C. Verb tense error. Result should be resulted.
D. Correct. Past perfect has been properly used to show the researchers expectation was prior to the result of the experiment.
E. Have expected is wrong.
D is correct

For B
Don't you think expectation must be before the results were out , and it doesn't need 'had' to highlight that?

Yes, expectations are before the result and that is why we have to denote the two time periods through PERFECT tense, as there is/are no words in the original sentence that separates specific times.

You can avoid PERFECT tense when you use words, such as before, after etc, that themselves clearly give us two time periods.

This can be written without past perfect as..
He finished his education in India before moving to LA.

(A) Neither result of the two experiments involving Alzheimer's patients were what the researchers have expected.
(B) Of the two experiments involving Alzheimer's patients, neither result was expected by the researchers.
(C) Neither of the two experiments involving Alzheimer's patients result in what the researchers expected.
(D) Neither of the two experiments involving Alzheimer's patients resulted in what the researchers had expected.
(E) What the researchers have expected was the result of neither of the two experiments involving Alzheimer's patients.

The answer is (D) . Let me illustrate the process I followed :

Meaning : Researchers expected something , result did not turn out likwise .

Since we have a comparison of a timeline and both are happening in the past , we need to have something that demonstrates the timeline . Past perfect generally is the most apt to illustrate the timeline of something that happened at past .

Here Past perfect refers to what researchers expected , and the past is used to mention the result of the experiment that appeared at a later point of time

Hence (D)

Kudos if you think the explanation helped

Can anyone please explain the reason why option "B" is incorrect.

Thanks in advance

OFFICIAL EXPLANATION



The correct answer is (D).

In the original version, the shift in time frame from past (were) to present (have expected) is confusing and illogical. Also, the syntax obscures the intended meaning; specifically, one could interpret neither result of the two experiments to mean that each of the two experiments had two results; but this is clearly not the intended meaning. Finally, the plural verb were does not agree in number with its singular subject neither result. Choice (D) remedies all of these problems.
