Explanation

When solving GMAT Sentence Correction Qustions, you should begin with grouping the Options

In the given sentence, Options A and B (one gruop) start with a subject, follwed by a present participial modifier-"declaring that".In Option A, the subordinate clause-"since most of the studies had failed to control for such variables as social class and family size"- is followed by a main clause-"none could be taken seriously". However, the Main Subject- " Swiss psychologists" does not have a verb.

In Option B also, the subject "Two Swiss psychologists" does not have a verb.Hence, Options A and B are eliminated.

Now, let us analyze the remaining options.

Options C, D and E start with a Subject follwed by a Verb.

Now, let us regroup these three options. In other words, we look for major differences in the remaing options.

In Option C, the subordinate clause does not have a stand alone (complete) verb.

In Option D, the verb in the subordinate clause "Fail" is in the present tense.

Finally Option E is the Best Option

The Strucure of the Best Sentence:

The sentence begins with four Modifiers: Three Prepositional Phrase-"In a review", "of 2000 studies", and "of human behavior"- and a Relative Clause-" that date back to the 1940's"

Then, the subject-verb follows. That is "Two Swiss psychologists declared that"

Then, a subordinate clause follows. That is: "since most of the studies had failed to control for variables such as social class and family size, "

Finally, a main clause is at the end of the sentence. That is "none could be taken seriously"
