Hi vishalmin,

My thought is that:

Split 1: parallel structure
"overestimate the amount of energy used by equipment" and "underestimate that used by
unobtrusive equipment" --> eliminate B, C and D

In A, "equipment" and "unobstrusive equipment" would be better if we use "visible equipment" and "unobstrusive equipment" to make parallel structure as in E.

Regards.

A and B: equipment...that are visible
Here, are (plural) does not agree with equipment (singular).
Eliminate A and B.

C and E: when used by unobtrusive equipment
Here, it is not crystal clear what is used by unobtrusive equipment.
Eliminate C and E.

The correct answer is D.

C and d are wrong --> Underestimate it...it has no referrence.

C and E can be eliminated for this reason.

Is there any preference visible equipment > equipments that is visible

C: the amount of energy used by equipment, such as lights
Conveyed meaning:
Lights are an example of EQUIPMENT.

OA: the amount of energy used by visible equipment, such as lights
Conveyed meaning:
Lights are an example of VISIBLE equipment.

Whereas C conveys that lights are an example of equipment IN GENERAL, the OA conveys that lights are an example of a SPECIFIC TYPE of equipment: VISIBLE equipment.
The intention here is to convey the latter meaning.

Hi Mitch,
Can you tell if the usage of when in C and E also problematic?
What exactly is the problem with when when used this way?

The intention here is to express the following GENERAL TRUTH:
People tend to underestimate the amount of energy used by unobtrusive equipment.
In C and E, the usage of when implies that people UNDERESTIMATE only at a specific moment: WHEN something is used.
Not the intended meaning.

Here, the second comma in red bears no relevance to the following that.
The purpose of this comma is to help set off the non-essential modifier in red.
If we remove the non-essential modifier, we get:
People tend to overestimate the amount of energy used by visible equipment that must be turned on and off.
The result:
No comma before that.

Hi GMATGuruNY ,

Thanks for you reply all clear now.
