Practice Question
Question No.: SC 10
Page: 659

Carnivorous mammals can endure what would otherwise be lethal levels of body heat because they have a heat-exchange network which kept the brain from getting too hot.

(A) which kept
(B) that keeps
(C) which has kept
(D) that has been keeping
(E) having kept


First Glance

The short underline features different forms of the verb keep. This problem must be testing verbs.

Issues

(1) Verb: kept; has kept; has been keeping

The changing verb tense at the end of the short underline is a big clue. When did the heat exchange network keep the brain from getting too hot?

In order to decide which verb tense or tenses are correct, you need to understand the meaning of the sentence. Mammals can endure the high body heat because they have a special characteristic.

Note that can and have are in the present tense. Unless there is a meaning-based reason to switch tenses (and here there isn't), keep should also be in the present tense. The mammals have a special characteristic that allows them (now, in the present) to stay cool. Eliminate answers (A), (C), (D), and (E).

The Correct Answer

Correct answers (B) uses the present tense verb keeps, which is consistent with have.

(A) which kept
(B) that keeps
(C) which has kept
(D) that has been keeping
(E) having kept

If which keeps was an option would you choose it ?


A "Kept" is wrongly in the past tense.
B Correct
C Past perfect is wrong here. Everything should be in the present tense.
D Past progressive is also wrong here.
E There is a dependent clause formed by the noun modifier here, yet with "having kept" that clause becomes a fragment.

Carnivorous mammals can endure what would otherwise be lethal levels of body heat because they have a heat-exchange network which kept the brain from getting too hot.

(A) which kept
(B) that keeps
(C) which has kept
(D) that has been keeping
(E) having kept

Endure meaning : suffer (something painful or difficult) patiently.

That without comma is used for essential modifiers while WHICH WITH COMMA is used for non - essential modifiers.

Also we are talking about a general concept so it must be in Simple present tense.

"That keeps" seems to be most suitable answer for this question.

Answer B

Hope it helps....


the question is checking verb tense primarily.
as the sentence clearly suggests that present simple tense is appropriate

(B) that keeps
(C) which has kept

(E) having kept



Main Issue:


1) Verb: Since a general fact is being stated with "can endure" (Simple Present tense), we need a verb in simple present tense in the modifier. All choices except B use a wrong verb.
