Resolving a long-standing controversy among neuroscientists, the recent discovery that tiny movements of the eye called microsaccades provide up to 80% of our visual experience provides incontrovertible support for the theory that visual perceptions are dependent on motion.


(A) are dependent on motion

(B) had been dependent on motion

(C) are phenomena which are dependent on motion

(D) had been phenomena dependent on motion

(E) are phenomena which had been dependent on motion

(A) are dependent on motion

(B) had been dependent on motion

(C) are phenomena which are dependent on motion

(D) had been phenomena dependent on motion

(E) are phenomena which had been dependent on motion
In this sentence we need to use the present tense because it is still happening now. So we can eliminated B, D, and E. The past perfect tense is used when we have two things which happened in the past and one happened before the other. For example: When I arrived at the party, Marry had gone home. (She left the party before I arrived there). Clearly, the visual perceptions are still happening now.

I'm not as confident between A and C, but I'm going with A because I don't think "are phenomena" is important to the overall sentence. Further, I don't think that visual perceptions are phenomena, so they are themselves dependent on motion.

What's the OA?

Resolving a long-standing controversy among neuroscientists, the recent discovery that tiny movements of the eye called microsaccades provide up to 80% of our visual experience provides incontrovertible support for the theory that visual perceptions are dependent on motion.


(A) are dependent on motion

(B) had been dependent on motion

(C) are phenomena which are dependent on motion

(D) had been phenomena dependent on motion

(E) are phenomena which had been dependent on motion



Options B, D and E are completely out of the box as 'had been' is not required' here in the sentence.

Kartik, it comes down between the options A and C,

the option C is incorrect as it is more wordier than the option A.

Delivers the same meaning using a wordier and more complex approach than what the option A does.

A is more simpler.

Also we have to choose the best answer out of the 5 answer choices given, and hence the correct answer is option A.

hope this helped you Kartik...
