It is an example of how tricky can gmat questions be.

Most of the people are intimidited by A but the problem is with "its", which refers to elephant's.

If the setence were not properly paralled without "that x ......... and that y ......", "its" is never be a clear referant for "elephant". That construction is only in E, which is tghe best and OA.


excellent posting for us to know.

(A) that suggests that the elephant is descended from an aquatic animal, and its trunk originally evolved
The sentence is trying to tell us that the evidence suggests two things: 1) that the elephant is descended from an aquatic animal and 2) that the elephant's trunk originally evolved as a kind of snorkel; in order to avoid a parallelism issue, we would have to change, "..., and its trunk originally evolved as a kind of snorkel" to "and that its trunk evolved as a kind of snorkel." Furthermore, this sentence has a string of relative clauses ("evidence that suggests that the elephant...", and the GMAT considers it "awkward and confusing to string together relative clauses." For these two reasons, choice A can be eliminated.

(B) that has suggested the elephant descended from an aquatic animal, its trunk originally evolving
The simple present tense ("suggests") should be used instead of the present perfect tense ("has suggested") because we are describing a present action (what is the evidence currently doing?) and not referring to what the evidence was doing in the past. Present perfect is typically used to describe how long an action has been going on, for example, "For the past 100 years, most evidence has suggested (present perfect) that the elephant is descended from a land animal; however, new evidence suggests (simple present) that the elephant is descended from an aquatic animal." Furthermore, a past tense should be used instead of "evolving" because we are talking about a past action (how the trunk evolved in the past, not how it is evolving now), so choice B can be eliminated.

(C) suggesting that the elephant had descended from an aquatic animal with its trunk originally evolving
This choice can easily be eliminated because the past perfect ("had descended") is not the appropriate tense (we do not have two past actions occurring at different times). Also, a past tense should be used instead of "evolving" (see choice B notes).

(D) to suggest that the elephant had descended from an aquatic animal and its trunk originally evolving
Again, the past perfect ("had descended") is not the appropriate tense. Also, this choice contains a parallelism issue ("its trunk originally evolving..." is not parallel to "that the elephant had descended.."), and a past tense should be used instead of "evolving" (see choice B notes).

(E) to suggest that the elephant is descended from an aquatic animal and that its trunk originally evolved
Here the infinitive "to suggest" is properly used as an adjective to modify "evidence". This choice also avoids parallelism issues ("suggest that the elephant is descended... and that its trunk originally evolved..."). The predicate adjective "descended" follows the linking verb "is" and properly modifies "the elephant". This might not sound right because we are used to hearing "descend" used as a verb (ie "I descended a flight a stairs."), but you shouldn't trust your ear when analyzing SC problems! Choice E is correct.

Australian embryologists have found evidence that suggests that the elephant is descended from an aquatic animal, and its trunk originally evolved as a kind of snorkel.

(A) that suggests that the elephant is descended from an aquatic animal, and its trunk originally evolved
(B) that has suggested the elephant descended from an aquatic animal, its trunk originally evolving
(C) suggesting that the elephant had descended from an aquatic animal with its trunk originally evolving
(D) to suggest that the elephant had descended from an aquatic animal and its trunk originally evolving
(E) to suggest that the elephant is descended from an aquatic animal and that its trunk originally evolved

One useful thing to remember in this context is the difference in meaning between is descended and has descended. Is descended is a linking or extant verb that denotes a state of being. There is no action involved in it. On the other hand, 'has descended' means going down effortfully as in descending from the top floor to the ground floor. There is an action involved in it. 'Is descended' is mostly used in genealogy and genetics, in which we refer to some traits that are derived from their ancestors. This knowledge will help us to get rid of B, C, and D. Now between A and E, it will not be difficult to dislodge A for using missing the 'that' //ism. It is E.

it should be "evolved" and not "evolving" so A and E remains. As per parallel structure A is correct.

B,C, and D have wrong tense issues as well.

[Reveal] Spoiler:
Although we certainly don't hear it often, "is descended" is correct. For example:

We are descended from the chimpanzee.
He is a direct descendant of Charles the Great.

But I do agree that the phrase looks odd on paper.





Is it fine to write "Australian embryologists have found evidence to suggests" . My understanding says that it should be "That" and not "To" "Australian embryologists have found evidence that suggests" . Please someone put some light on this .

Hello gmat4varun,

Thank you for the query. :-)

The correct official sentence uses the expression Australian embryologists have found evidence to suggest. We know that the correct answers of official sentences are always correct. Hence, we should not doubt them. Rather, we should learn from them those correct usages we are not aware of.

See, there is no issue in the expression Australian embryologists have found evidence that suggests. Undoubtedly, this expression conveys the intended meaning clearly. However, there is no issue with Australian embryologists have found evidence to suggest either.

Hope this helps. :-)
Thanks.
Shraddha

[quote="BM"]Australian embryologists have found evidence that suggests that the elephant is descended from an aquatic animal, and its trunk originally evolved as a kind of snorkel.

(a) that suggests that the elephant is descended from an aquatic animal, and its trunk originally evolved
(b) that has suggested the elephant descended from an aquatic animal, its trunk originally evolving
(c) suggesting that the elephant had descended from an aquatic animal with its trunk originally evolving
(d) to suggest that the elephant had descended from an aquatic animal and its trunk originally evolving
(e) to suggest that the elephant is descended from an aquatic animal and that its trunk originally evolved

only choice E make "its truck" refer to "elephant". in other choices, "its trunks" are ambiguous.
choice E use second "that" , so,the clause "its trunk evolve...." is parallel to "elephant is..." . and because of this paralelism, "its trunk" refer clearly to "elephant".

Australian embryologists have found evidence that suggests that the elephant is descended from an
aquatic animal, and its trunk originally evolving as a kind of snorkel.

A. that suggests that the elephant is descended from an aquatic animal, and its trunk originally evolving
The evidence suggested 2 things (i) that the elephant ….and (ii) that its trunk ….
However, the second “that” is missing in the sentence.
Also, we need a verb in place of a verb-ing “evolving”

B. that has suggested the elephant descended from an aquatic animal, its trunk originally evolving
“has suggested” incorrect Tense.. We need simple present tense to express that the evidence suggests X and Y..

C. suggesting that the elephant had descended from an aquatic animal with its trunk originally evolved
“evidences that suggesting that” !!!
Pretty awkward…
“evidence suggesting that” would have been better ..
Also the usage of “with its …” is incorrect as this should be a separate clause to emphasize that the evidence suggests two things…

D. to suggest that the elephant had descended from an aquatic animal and its trunk originally evolved
As clarified in Option A second “that” is missing

E. to suggest that the elephant is descended from an aquatic animal and that its trunk originally evolved
Correct

Hey All,

I got asked to take this one on by private message, so here I am! The answer is certainly E.

Australian embryologists have found evidence that suggests that the elephant is descended from an aquatic animal, and its trunk originally evolved as a kind of snorkel.

(A) that suggests that the elephant is descended from an aquatic animal, and its trunk originally evolved
PROBLEM: There's no reason to use a comma with a list of two things.

(B) that has suggested the elephant descended from an aquatic animal, its trunk originally evolving
PROBLEM: You have to say "that" after the verb "to suggest".

(C) suggesting that the elephant had descended from an aquatic animal with its trunk originally evolving
PROBLEM: The use of the past perfect tense here is incorrect, because the action isn't complete. I know it may seem like the descent has ended, but in the present, the elephant is STILL descended from an aquatic animal. That's an eternal truth. Also, using the prepositional phrase "with its trunk originally evolving" ends up modifying "an aquatic animal", when we really want to be referring to the elephant.

(D) to suggest that the elephant has descended from an aquatic animal and its trunk originally evolved
PROBLEM: We don't want to change tense in parallel unless there's a significant reason ("yesterday I went to the store but today I will stay at home"). No good reason from present perfect "has descended" to past "evolved".

(E) to suggest that the elephant is descended from an aquatic animal and that its trunk originally evolved
ANSWER: "descended" and "evolved" are parallel, and everything else is clear.

Hope that helps!

I thought commas will not be tested in gmat?
What makes A wrong is the commas, right?

A is not parallel in not only logic but also grammar because of "and".
