The intricate structure of the compound insect eye, having hundreds of miniature eyes called ommatidia, help explain why scientists have assumed that it evolved independently of the vertebrate eye.

A having hundreds of miniature eyes called ommatidia, help explain why scientists have assumed that it
B having hundreds of miniature eyes that are called ommatidia, helps explain why scientists have assumed that they
C with its hundreds of miniature eyes that are called ommatidia, helps explain scientists' assuming that they
D with its hundreds of miniature eyes called ommatidia, help explain scientists' assuming that it
E with its hundreds of miniature eyes called ommatidia, helps explain why scientists have assumed that it


This sentence addresses why scientists have decided that the vertebrate eye arid the insect eye evolved independently of each other. The insect eye is much more intricate, with hundreds of miniature eyes. The sentence needs to be clear as to what has hundreds of miniature eyes. The structure or the insect eye? Furthermore, the singular subject intricate structure requires the singular verb helps.

Option B is out for the same reason as given in Option A.

daagh Can singular pronoun it refers to Eye which is in preposition structure?

daagh wrote:
A case of SV mismatch and pronoun ambiguity and reference. The subject is the singular structure and the verb therefore should be helps, which is three in B, C and E. In B. the plural pronoun, they refer to anything plural but what is in issue is the singular insect eye that is compared with vertebrate eye. C also has the same pronoun mis - reference as in B. E remains with the use of the singular verb helps and singular pronoun it

Here are my two cents:
Yes, the rule which you are referring might be pointing that the prepositional phrase can not take subject of the verb.
Here : of the compound insect eye is the prepositional phrase can not determine the verb, but the verb is determined by:
The intricate structure of the compound insect eye. The pronoun (even modifier) can refer back to the subject in prepositional phrase.

Can a Pronoun refer to a Noun that is a part of a prepositional phrase


Doubt- How "it" can refer to "trouble" because "trouble" is a part of a prepositional phrase that acts as an Adjective - so how a Pronoun can refer to an adjective?

Dear DAakash7,

I'm happy to respond.

With all due respect, my friend, you are strictly following a rule that simply does not exist. I don't know whether some faulty source suggested that this should be a rule, but it's not. Grammar is hard enough! Don't complicate it further by introducing rules that don't exist!

Any noun anywhere in the sentence, in any role, can be the antecedent of a pronoun, as long as the noun is not in the possessive form. It doesn't matter whether the noun is the subject, the object of a verb, or the object of a prepositional phrase.

Hadyn's symphonies are ..... and he thought .... = mistake: antecedent in the possessive

The symphonies of Haydn are ... and he thought ... = 100% correct

It doesn't matter that "of Haydn" has more or less the same logical meaning as "Haydn's." The latter is in the possessive form, and cannot be an antecedent, but the former is not in the possessive form, so it can be the antecedent.

Does all this make sense?
Mike

Thanks a lot GmatClub.


hi

having = have + ing = verb + ing.
verb-ing modifiers are very versatile modifiers.
there are two case


if verb-ing modifiers appear after a clause and is preceeded by comma ,then it modifies the entire preceeding clause.It
a) either presents additional information about the preceeding clause or
b) result of the preceeding clause.


if verb-ing modifiers appears without a comma==>it modifies the immediate noun.

now in our question:

The intricate structure of the compound insect eye, having hundreds of miniature eyes called ommatidia, help explain why scientists have assumed that it evolved independently of the vertebrate eye.

so according to rule HAVING is modifying the entire preceeding clause....
so in this sentence ...meanig coming out: intricate structure are having hundreds of miniature eyes==> this is illogical as structure cant have eyes...
hence we can eliminate all the option using HAVING


please refre to this also.

hope it makes sense now.

Hi kanthaliya


Hi well the verbing modifier here is certainly used in the role to modify preceding noun, but we have two noun's in preceding noun phrase 'the intricate structure' and Compound insect eye. Well i don't know if structure can have miniature eyes or compound insect eye can have miniature of eyes. Both seem logical to me . ( but i did research on the insect eye, having miniature of eyes should refer to compound insect eye)

intricate structure are having hundreds of miniature eyes We have SV does not agree in number error here.
Say we had the below clause

(A)intricate structure is having hundreds of miniature eyes

(B)compound insect eye is having hundreds of miniature eyes

Can we say A is right and B is wrong,or B is right or A is wrong.

(C)Structure of Insect eyes , in which insect eye is having blah blah blah, helps explain blah blah

(D)Structure of Insect eyes , in which structure is having blah blah blah, helps explain blah blah
Logically if you see C make more sense than D.

Now, since we have this ambiguity we can get rid of this with a better choice.

I am sure you must have spotted other errors with this option

Note both Options A and B are wrong for several other reasons too .
Option A: Apart from Modifier ambiguity , the singular subject “structure” doesn’t agree with the plural verb “help”.

Option B : Apart from modifier ambiguity we have "they” refers to “miniature eyes”, which is not the logical referent .we need a singular pronoun to refer to compound insect eye.
Also note "that are called ommatida" is unnecessary as it makes the choice too wordy. the original sentence did convey the same information in precise manner.

Hope this helps

Hi daagh,
How can someone know/convinced (apart from meaning) that ''it'' does not indicate ''the intricate structure'' in E?
Thanks__

Hi!

In the OG, says that the pronoun "IT" of answer choice E refers back to the noun "the compound insect eye." Is that possible? I thought the pronoun has as an antecedent the singular noun "structure." Can we refer to the noun in the prepositional phrase "of the compound insect eye" ???

Hi daagh egmat
In the correct choice E, I thought "why" shouldn't be used as a pronoun because it's a question form.
I think many of the choices in other SC questions were rejected because "why" was used as a pronoun.

1. It is not clear whether 'why' is ever used as a pronoun. At least I don't remember an example off-hand. If it were a pronoun, one should be logically able to explain what that pronoun stands for. We can't find a suitable noun in this given context. We can see it as an adverb of reason at best.
2. Declarative statement form: I don't know when he will appear for the test
Question form: When will he appear for the test?

One may also note that if it were a question, then the sentence should end with a question mark.

Sentence Analysis:
The intricate structure of the compound insect eye, having hundreds of miniature eyes called ommatidia, help explain why scientists have assumed that it evolved independently of the vertebrate eye.

SV error, intricate structure (Singular) - help (Plural)
Modifier error, Verb + Ing- having with comma is working as cause and effect, which is not right. Any verb +ing for explaining more about the subject shall be used without comma.

So option And B are out.

Option C, "that are called" - wordy. and they is plural but it is still defining the structure.

Option D, "help" should have been "helps"
