This question is very easy to answer if the non underlined part is read carefully.

A. coral reefs provide a host of benefits that includes the supply of protein for people, protecting shorelines, - Incorrect - Parallelism error + Singular form 'includes' is used instead of 'include'

B. coral reefs provide a host of benefits: they supply people with protein, they protect the shorelines, - Correct

C. coral reefs provide a host of benefits that include supplying protein for people, as well as shoreline protection, - Incorrect - Parallelism error

D. a coral reef provides a host of benefits; they supply protein for people, the protecting of shorelines, - Incorrect - Same error as C

E. a coral reef provides a host of benefits, including protein for people, protecting shorelines, - Incorrect - Same error as D

Quick look at the end of underlined portion shows 'and they' so that is a hint at looking for parallelism right before it.
Only B does this, in the 'they + verb' format

'They' in non underlined part preceded by 'AND' indicates that we need parallel elements with 'they' mentioned in it.

Only choice B fulfill this requirement.

Another thing we have here is "a host of benefits that include/includes".
I think a host of issues will be plural. So we should have "host of benefits that include".
Just like "The are a host of issues".

Am i correct?

Hi All,

While i agree that B is the best option available and it stands second to none, I have a concern with how it has been worded. The second clause in the list says " supply people with protein", does this not mean that the coral reefs supply "people" with protein ( people who have protein) ?

I definitely see an ambiguity in the way this option has been constructed. Looking forward to more opinions.

Thanks and Regards,
Shradha

Nearly unrivaled in their biological diversity, coral reefs provide a host of benefits that includes the supply of protein for people, protecting shorelines, and they contain biochemical sources for new life-saving medicines.

Issues: Parallelism | Subject-Verb Agreement

Analysis:

1. The sentence talks about benefits of coral reefs.
2. The clauses that follow after colon(:) should be parallel. Parallelism alone can be used to eliminate all the options except (B).
3. Another issue with original sentence is the usage of singular "includes" with plural benefits.


I have highlighted the issues below:

A. coral reefs provide a host of benefits that includes the supply of protein for people, protecting shorelines,
- Subject-Verb agreement
- Parallelism issue

B. coral reefs provide a host of benefits: they supply people with protein, they protect the shorelines,

C. coral reefs provide a host of benefits that include supplying protein for people, as well as shoreline protection,
- parallelism issue

D. a coral reef provides a host of benefits; they supply protein for people, the protecting of shorelines,
- pronoun "their" in non-underlined portion of the sentence requires a "plural" subject. Hence singular "a coral reef" is incorrect
- parallelism issue

E. a coral reef provides a host of benefits, including protein for people, protecting shorelines,
- pronoun "their" in non-underlined portion of the sentence requires a "plural" subject. Hence singular "a coral reef" is incorrect
- parallelism issue

Answer: B

A. coral reefs provide a host of benefits that includes the supply of protein for people, protecting shorelines,
parallelism is at issue. non underlined part says ",and they" so we need parallelism as given in choice B.

B. coral reefs provide a host of benefits: they supply people with protein, they protect the shorelines,
they supply, they protect ...., and they contain --- correct parallelism.

C. coral reefs provide a host of benefits that include supplying protein for people, as well as shoreline protection,
same issue as in A.

D. a coral reef provides a host of benefits; they supply protein for people, the protecting of shorelines,
their diversity would require reefs not reef as referent

E. a coral reef provides a host of benefits, including protein for people, protecting shorelines,
their diversity would require reefs not reef as referent

Hi experts mikemcgarry

could you please provide your comments for option B? I have reached by poe.

I think B is having meaning issue. they supply people with protein ( but we want to say supply protein to people).

Please clarify this.

Thanks.

Coral reefs is not a collective noun, if was then reefs should be starting with capitol R, subject verb agreement is correct.Host of benefits' is singular and correct.

Protecting is not parallel, after elimination based on the above factore Option B is left.

Hello PathFinder007,

I am not sure if you still have this doubt. Nonetheless, here is the answer.

Choice B does not lead to meaning change. See, it is very obvious that humans consume protein. It is definitely not the other way round.

So saying supply protein to people is similar to saying supply people with protein because what is being supplied is protein, and the receiver are people.


Hope this helps. :-)
Thanks.

Hello experts ,

I have a doubt in correct option B
after colon the three parallel elements form clauses
--> they supply people with protein, they protect the shorelines, and they contain..

don't we need a conjunction between first and second clause? Last one forms an independent clause and is connected to the rest of the sentence with "and". I understand that parallelism is better but I fail to understand the sentence structure.
If the statements are part of a list, shouldn't it be written as they supply .. , protect ... , and contain..?

Also could you please explain the error in option C?

Hi there !

While I agree that option 2 is the best available option, isn't it flawed as well ?

"..:they supply people with protein, they protect the shorelines, and they contain biochemical sources.." Here shouldn't each independent clause be connected by a comma + conjunction (rather than just a comma) to be grammatically correct ?

For me the below is more appropriate - " :they supply people with protein and protect the shorelines, and they contain biochemical sources.."

Thank you for your time!

this question is a perfect example showing that ambiguous pronouns sometimes are fine in gmat questions. Also, test takers should know that such ambiguous pronouns are counted as a common pattern in gmat.

Hello srinivasosuri and rtlko,


Since both of you ask the same question, here is my response for both of you in the same post.

It is true that we go by the rule that independent clauses must be connected by specific conjunctions to keep the structure of the sentence grammatical.

However, this sentence is certainly the exception to this rule. And this is what I feel is the beauty of official questions. There is always something new to learn from these sentences. :-)

In answer Choice B, the three independent clauses have been used as parallel elements in the list. If we follow the strict connection rules for these independent clauses, the structure will certainly violate the structure followed to present the parallel list. This is the reason why all the first two independent clauses are connected by a comma as any other elements would be connected, and the last element is preceded by comma + and, the typical connector to join more than two parallel elements in the list.


Once again, the correct answer choice of this official sentence drives the fact home that no answer choice should be rejected or accepted solely on the basis of the usage of punctuation mark.


Hope this helps. :-)
Thanks.
Shraddha
