Hello experts ,

Also could you please explain the error in option C?



Hello rtlko,

I am not sure if you still have this doubt. Here is the explanation nonetheless. :-)

Per the original sentence, the benefits include three items:
    the supply of protein for people,
    protecting shorelines, and
    they contain biochemical sources for new life-saving medicines


Although the above-mentioned list is not grammatical, it does convey the intended elements meat to be parallel.

However, per choice C, there is no list of benefits. This choice presents the first benefit that is followed by the second intended benefit just as an additional point.

The third intended benefit actually appears as a separate information about the the coral reefs altogether. It does not appear to be the part of the list of benefits. This structure leads to chnage in meaning error in Choice C.


Hope this helps. :-)
Thanks.
Shraddha

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?


IMHO thats a good observation and undoubtedly correct...


Hi Abhishek,

Hello sunny91,


I have already explained the reason for missing conjunction before FANBOYS in the correct answer choice B.

Following is the explanation:

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

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

Answer: B


option A:a host of benifits that...
here THAT refers to the head of noun phrase which is singular and thus the use of singular verb "includes" is correct

Is using WITH right here? It doesn't change the intended meaning?

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!

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.

A. coral reefs provide a host of benefits that includes the supply of protein for people, protecting shorelines,
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,
D. a coral reef provides a host of benefits; they supply protein for people, the protecting of shorelines,
E. a coral reef provides a host of benefits, including protein for people, protecting shorelines,



THERE ARE FEW MORE OBSERVATIONS , which I thought would help others:

It is sometimes beneficial to look at non-underlined part as well as it gives subtle hints.

Nearly unrivaled in their biological diversity

Now the subject has to be plural because non-underlined part has pronoun their in it.


This literally eliminates Option D and E as the use of verb "Provides" confirms "Coral reef" is singular. If we use singular subject , the pronoun used earlier will have no antecedent. So one doesn't even have to check for parallelism on these 2 options.
