D the horny jaws function [strike]as teeth do[/strike]
E the horny jaws function as teeth

explain your choices ..


Question - between their and its... what would have been used ?


I think 'their' would be correct as subject is plural in the second clause.

I believe the correct idiom is function as... so a,b, and c are out
Between D&E, D changes the meaning to say that the jaws perform the same functions as teeth do (the jaws chew), whereas E retains the original meaning that the jaws act as teeth -> so E

agree ..OA is E ..

but what if my intension was to just compare the function(as it did in option D)? how/what is the correct way to write that sentence?

Second sentence refers to turtle species so B and C are out due to "its"
function for is not correct so A is out.
D has parrallel problem. What does teeth do?
E is correct. In some turtle species the sharp and edges of their jaws function as teeth.

Between C,D,E??
The it is said to work as a possesive poison..this is not clear..please explain in detail

found this


"some contemporary turtle species", is an adverbial modifier so cannot be the main subject of the sentence

Hey All,

Seems like there's still confusion on this one, so I thought I'd weigh in. There are two important splits to deal with here. The first is pronoun (singular/plural and pronoun/versus no pronoun) and the second is idiomatic.

"Although the turtle has been toothless for more than 150 million years" has no bearing on the rest of the sentence. The next clause begins with a new subject "some contemporary turtle species" (which is not an adverbial modifier, by the way), which is the most logical antecedents for any pronoun. Species is plural, so we would need "their", or else to remove the pronoun altogether. This is better, because there would be definite confusion between the two possible antecedents (turtle, species) anyway. From there, we need the right idiom, which is "x functions as y". There's no need for the verb "do", because that's obvious (i.e. I can say "The Tacoma Narrows Bridge ended up functioning as a real-life physics experiment", and don't need to say "The Tacoma Narrows Bridge Ended up functioning as a real-life physics experiment does".

This gets us to answer choice E.

Hope that helps!

Thanks for the explanation . Tommy, however ben ku ( MGMAT instructor) has mentioned that as adverbial modifier and there not the main subject.

http://www.manhattangmat.com/forums/gma ... t1321.html

would you mind explaining some adverbial modifiers to differentiate from above ?

Aha,

I understand now! It is indeed a modifier, though of the prepositional phrase variety (adverbial in that the verb "function" is being modified). You'll want to avoid referring to nouns in such phrases. For example:

I ran for two hours on the beach yesterday, because ITS sand was so soft.

Even though the "ITS" clearly refers to beach, there's no need to use a possessive pronoun here ("on the beach" is another prepositional/adverbial modifier). Better just to say:

I ran for two hours on the beach yesterday, because THE sand was so soft.

Hope that's clearer! Thanks for the follow-up!

Its E - correct idiom usage - Jaws FUNCTION as teeth - "Function as Y" does not need DO. There is no explanation for it.

Hi folks,

I’m afraid the correct answer for this one is choice E and not choice D.

Although the turtle has been toothless for more than 150 million years, in some contemporary turtle species the moderately sharp and jagged edges of their horny jaws function for teeth.

Per the context of the sentence, it is not difficult to understand that here turtle’s “horny jaws” are NOT compared to “teeth”. The horny jaws actually play the role/function of teeth. Hence, this sentence presents function of horny jaws.

PoE:

A. their horny jaws function for teeth: Incorrect.
1. Plural pronoun “they” does not agree in number with singular “turtle”.
2. Use of “for” is incorrect.

B. its horny jaws function for teeth: Incorrect. Use of “for” is unidiomatic.

C. its horny jaws function as do teeth: Incorrect. Notice that “as” is followed by a clause here, presenting comparison. This is not correct because the sentence does not compare the horny jaws with teeth.

D the horny jaws function as teeth do: Incorrect. Same as choice C.

E the horny jaws function as teeth: Correct. When “as” is used to present role/function of something/someone, it is followed by a noun entity. Here “as” is correctly followed by noun entity “teeth”. Hence, this is the correct answer.

P.S: To be able to get rid of the confusion of when to use “as” and when to use “like”, read the article by clicking on the following link:

Hi Egmat,

Is species singular or plural?

Hi Srinath,

The word "species" is the singular as well as the plural. It can be used as both.

Hi Shraddha,
I think that here we are comparing the moderately sharp and jagged edges(say,X) of the horny jaws(say,Y) function as teeth do. X of Y-then X is the subject I guess.So here the sharp and jagged edges work as the teeth do.(Not comparing the horny jaws with teeth)

Then would you please elaborate why D is wrong ?

Much help appreciated.
