In their ability, having the ability or having their ability are all inferior to "are able" as per the V-A-N rule. So, D
_________________

To show the reason of Turtle's survival, we need 'because'. A, B and C are out

'able to' is the correct idiom. E is out

D is the answer

Answer must be (D) , reasons highlighted below -

Turtles, like other reptiles, can endure long fasts because they are able to survive on weekly or even monthly feedings; however, when food is readily available, they may eat frequently and grow very fat.

The red part in options B,C and E just doesn't sound right to my ear. But, I am not able to pinpoint the error(s). Can you please help me do that.

Thank You!

B) “having” and “being” are awkward in general, and should normally be avoided because they are passive / wordy.
C) same as B but more wordy
E) same as C

Can we think of any other reasons apart from generalising "having" and "being" as awkward. I find it really hard to eliminate such options on ground of pure logic.

It's not just awkward; it's also wordy and passive.

"Because of there being no other explanation, this is the best reason that I have."

vs.

"This is the best reason I have, because there is no other explanation."

I think that the 2nd choice is obviously better here.

In C & E, "ability of" is not used correctly. "ability to" is the correct usage. For B, the only reason for me is also "not sounding correct"

Thanks

I have a doubt here.

Normally being and having considered passive, we avoid them. Apart from this , we have ability to do something is a right idiom. ; Hence we left out with A and D.

I am not able to find any mistake in A, apart from being awkward. Had the sentence written as

In their ability to survive on weekly or even monthly feedings , Turtles, like other reptiles, can endure long ​​fasts.

Would this be still awkward to you.

What is the other error , which I am missing in A.

Yes it would still be wrong. "In their ability" does not make any clear sense. Consider the following:
He can solve mathematical problems fast in his ability to analyse systematically........ this sentence does not make any clear sense.
He can solve mathematical problems fast because he is able to analyse systematically..... correct.

Thanks for the reply and correct answer,

And for the reader i'd like to add that

VAN stands for verb > adjective > noun.It says if we are stuck between two options.in that case we should prefer verb over adjective or noun

My two cents -

Option A reads something like this -

"in their ability to survive ..., turtles can endure long fasts". The preposition "in" seems to imply that "can endure long fasts" is part of their ability to survive. Does not make sense.

Option B -
"having their ability ..." - I think that "their" is unnecessary. It is obvious that turtles have their own ability.

Option C -
"due to" is a noun modifier. It illogically modifies "long fasts". long fasts are not due to the turtle's ability.
"ability of surviving" is not idiomatic.

Option D -
correct answer. "because" brings out the causal relationship quite clearly.

Option E -
ability of surviving is unidiomatic.
_________________

look at E

"Because of doing" involved a hard point of grammar which I dont want to explain here. it take many words to explain this wrong pattern. because the use of doing as participle and gerund is hard to apply.

for simplicity, we can memorize a hard and fast rule. use this rule without considering meaning

"because of+doing+direct object"
is alway wrong on gmat.

because of learning English well , I pass gmat

this is wrong .

so, choice E is wrong.

OFFICIAL EXPLANATION

To express why turtles can endure long fasts— their ability to survive on only occasional feedings—it is clearer and more idiomatic to use because than to use in or having. Also, the noun ability here requires to introducing a noun phrase denoting the nature of the ability.
A In does not express the causal relationship clearly, whereas because does.
B Having does not express the causal relationship clearly.
C Ability of is incorrect; ability must be followed by to in order to express the intended meaning. Due to having the ability is awkward, nonstandard, and unnecessarily wordy.
D Correct. is option uses because to express the causal relation and uses to after ability.
E Ability of is incorrect; ability must be followed by to in order to express the intended meaning. Because of having the ability is awkward, nonstandard, and unnecessarily wordy.
e correct answer is D.

A) fasts, in their ability to survive
B) fasts, having their ability to survive
C) fasts, due to having the ability of surviving
D) fasts because they are able to survive (correct)
E) fasts because of having the ability of surviving

Hope this helps

Hello Everyone!

Let's take a closer look at this question to get to the correct answer quickly! Before we dive in, here is the original question, with major differences highlighted in orange:

Turtles, like other reptiles, can endure long fasts, in their ability to survive on weekly or even monthly feedings; however, when food is readily available, they may eat frequently and grow very fat.

A) fasts, in their ability to survive
B) fasts, having their ability to survive
C) fasts, due to having the ability of surviving
D) fasts because they are able to survive
E) fasts because of having the ability of surviving

While it looks like the bulk of each option is different, there are a couple things we can focus on to narrow down our options:

1. ability to survive / ability of surviving
2. because / due to / in having

Since #1 on our list will eliminate 2-3 options quickly, let's start there!

Whenever we talk about someone's ability + action, we MUST use the idiomatic phrase "ability TO" or "able TO." In English, we do not say that someone has the "ability OF" anything. Let's figure out which options use this correctly, and eliminate the ones who don't:

A) fasts, in their ability to survive --> OK
B) fasts, having their ability to survive --> OK
C) fasts, due to having the ability of surviving --> WRONG
D) fasts because they are able to survive --> OK
E) fasts because of having the ability of surviving --> WRONG

There you go - we can eliminate options C & E because they don't use the correct format "ability TO." This was a quick way to knock a couple options off the list!

Now, let's tackle #2 on this list, which is how to best show the intended meaning. If you read carefully, we're looking at a cause/effect relationship:

Cause: Turtles can survive on weekly or monthly feedings.
Effect: Turtles can endure long periods of fasting.

Since the ability to survive on weekly or monthly feedings is a REASON for them enduring fasts, we need to make sure the wording shows this clearly and without being overly wordy. Here is how the remaining options stack up:

A) fasts, in their ability to survive

This is INCORRECT because it doesn't clearly state that living on weekly and monthly feedings is a REASON for why they can endure fasting periods. It almost sounds like the sentence is saying it's typical for them to endure fasting because they ALWAYS have to live with weekly or monthly feedings, which isn't true.

B) fasts, having their ability to survive

This is INCORRECT because it also doesn't clearly show that this sentence is presenting a REASON why turtles can withstand fasting periods. It also sounds awkward and overly wordy, which is a red flag on the GMAT that the option is likely wrong.

D) fasts because they are able to survive

This is CORRECT! The word "because" makes it very clear that the sentence is providing a REASON. It also uses the pronoun "they" to further clarify we are talking about turtles specifically.

There you go - option D is the correct choice! It's clear, concise, and uses the correct idiomatic format of "able/ability to."


Don't study for the GMAT. Train for it.

What is V-A-N rule daagh
can you please explain or give some link

V-A-N rule has more to do with style than grammar. It means when opportunity calls for, prefer to use a verb as the first choice, over an adjective and then lastly a noun. It also implies that we prefer an adjective to a noun. Although it is not widely used, we can have it as a confirmatory tool

Order of protocol:

1.

Tom can swim faster than Dick can -- can swim is a verb
Tom is able to swim or capable of swimming faster than Dick -- able to swim is an adjective
Tom has the ability to swim faster than Dick-- has the ability is a noun.

2.

Turtles, like other reptiles, can endure long fasts, in their ability to survive on weekly or even monthly feedings; however, when food is readily available, they may eat frequently and grow very fat.

A) Fasts, in their ability to survive --- 'ability' as a noun is inferior to 'able' in D, which is an adjective.

B) fasts, having their ability to survive -- 'their 'ability'' as a noun is inferior to ' are able' in D, which is an adjective.

C) fasts, due to having the ability of surviving--- same as in B.

D) fasts because they are able to survive --- 'are able' is better than having 'their ability' - correct choice

E) fasts because of having the ability of surviving --- 'ability of' is a noun and inferior to choice D which uses the adjective 'able'

there are many official answers on og books, which show that comma+doing can show a reason for the main clause. this means comma+doing can be interchangeable with because-clause.

B is wrong because of redundance.
"having" refering to the subject and the meaning is
turtles have their ability. it should be "turtles have an ability. so, this is redundance.
if choice B is "having an ability to survive... " , it will be correct.
