differentiate between A and B --> only E has this structure, and thus E is correct

...differentiated between latent semantic indexing, which is ... , and vector space models, which can ...

Ans is E for using the correct idiom ''between X and Y"

The right answer is option E.

Meaning: A well-respected computer scientist differentiated between latent semantic indexing and vector space models.

This question tests the idiom between X and Y. X is latent semantic indexing and Y is vector space models.
The right idiom is between X and Y and not between X with Y. Eliminate B based on wrong idiom usage.
We have two things, X and Y. between rather than among is required. Eliminate option C.
In D, we have differentiated X and Y. This is incorrect. At best it should have been differentiated X from Y. A says differentiate X with Y erroneously. Eliminate options A and D.
We are left with option E as the correct answer. It rightly uses the idiom between X and Y.

The correct idiom — “ differentiated between x and y ”

In B, ... differentiated between latent semantic indexing ... with vector space models — is not idiomatically correct

In E, everything seems correct

Idiom between X and Y. Is correctly used in option E

In option A the two techniques is not compared correctly

In option B idiom use is incorrect

In option C use of among is incorrect

In option D same error of A is repeated

OFFICIAL EXPLANATION

There are two issues being tested in this question.

(1) The phrasing used in the original question (differentiated x with y) is not idiomatically correct and should be replaced by the correct idiom (differentiated between x and y)

(2) In order to ensure clarity and improve flow, the sentence should be constructed so that the format is consistent:
differentiated between X, {description of X}, and Y, {description of Y}

A. the phrase differentiated latent semantic indexing...with vector space models is not idiomatically correct (i.e., the correct idiom is: differentiated between x and y)

B. the phrase differentiated between latent semantic indexing...with vector space models is not idiomatically correct (i.e., the correct idiom is: differentiated between x and y)

C. the phrase differentiated among implies that more than two objects are being compared, which is not true is this case; so, differentiated among is improperly used

D. the phrase differentiated latent semantic indexing...and vector space models is not idiomatically correct (i.e., the correct idiom is: differentiated between x and y)

E. the phrase differentiated between latent semantic indexing...and vector space models is idiomatically correct as it follows the idiom differentiated between x and y
