I have a question regarding option B and C "that are called" is unnecessary. Option E is best

I want to know why these options are incorrect B and C

Look for the split consisting of the S-V pair for 'Structure'

The original sentence uses the verb 'HELP' (Plural) for the subject 'STRUCTURE' (singular)

'Structure' should use the singular verb form HELPS

Option B,C and E use 'HELPS'

But options B and C use the plural pronoun 'THEY' to refer back to the singular noun 'STRUCTURE' instead of using the the singular pronoun 'IT'

Hence, since only option E satisfies condition of S-V pair and proper use of the pronoun - ANSWER= E

Thanks I was aware of those errors ( easy to spot) but I'm interested in the usage of that over here and want to know if the usage is incorrect?

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.

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
E with its hundreds of miniature eyes called ommatidia, helps explain why scientists have assumed that it

============

the use of the clause starting relative pronoun "that" correctly modifies the preceding noun "miniature eyes"

miniature eyes
that are called ommatidia ( modifies miniature eyes )

the use of past participle "called" also modifies the preceding noun "miniature eyes"

miniature eyes
called ommatidia (modifies miniature eyes)

Both are grammatically correact and convey the same meaning.

Right off the bat, the subject is structure so the verb needs to be in singular (helps, not help). A and D gone.

B) "that" is superfluous, "why scientists have assumed" is wordy and awkward. Furthermore, "they" incorrectly modifies "eye". They should be "it". B gone

C) "explain scientists' assuming that" is wordy and awkward. And once again, "they" incorrectly modifies "eye", they should be "it".

E) "explain WHY scientists HAVE assumed" is correct, we have a past participle with the correct HAVE form, since it's in reation to scientists, which is plural. Also, "it" at the end correctly refers to "eye", which is singular. Thus, E is correct.

ı have a question with the part "miniature eyes called ommatidia". Shouldn't it be as "miniature eyes that/which are called ommatidia" because it is a passive structure, eyes can not call themselves as ommatidia ?

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

They part is not clear can you help me further?

What evolved independently of the vertebrate eye? -- the compound insect eye (=singular). "They" would refer to the miniature eyes, making the comparison incorrect.

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.

A. having hundreds of miniature eyes called ommatidia, help explain why scientists have assumed that it
having..modified subject of the preceding clause "The intricate structure" and meaning looks like The intricate
structure has miniature eyes(insect eye has miniature eyes).so this option is out

B. having hundreds of miniature eyes that are called ommatidia, helps explain why scientists have assumed that they
Option B is out for the same reason as given in Option A.

C. with its hundreds of miniature eyes that are called ommatidia, helps explain scientists' assuming that they
The intricate structure ...helps(correct). they(plural) is refer to back to The intricate structure(singular)..so
Incorrect

D. with its hundreds of miniature eyes called ommatidia, help explain scientists' assuming that it
The intricate structure ...help(incorrect)

E. with its hundreds of miniature eyes called ommatidia, helps explain why scientists have assumed that it
The intricate structure ...helps(correct).It refers to The intricate structure...Correct.

if doing is used as a noun, we can use possesive. but we use doing as a noun only when there is no dedicated noun, when there is no "learnation".

"assumption" dose exist, so we can not use "assuming"as a noun.

"assuming" used to refer to action of a specific agent in the sentence, (called participle), do not take possesive.

"assuming" in d is wrong.

"Having" and "with", surprisingly, isn't a split. Both of them carry the same descriptive meaning.

Here, 'with' modifies compound eye. We need to remember that 'with' modifiers are versatile.

E with its hundreds of miniature eyes called ommatidia, helps explain why scientists have assumed that it

Meaning=>the author is talking about the intricate structure of compound insect eye that have hundred of miniature eyes called ommatidia (probably thats why this is compound eye). this structure helps explain why scientist have assumed that it (insect eye) evolved independently of vertebrate eye.

point to remember
1. comma+verb+ing (having...ommatidia) is modifying the intricate structure which is illogical. it should refer to insect eye.
2. it is logically referring to "insect eye"not "intricate structure". so "it" is not ambiguous here.

error in original sentence: SVA and modifier
A=> modifier error and SVA error
B=>modifier error and "they"(plural) refer to "insect eye" (singular) ( some people say that "they refer to scientist so it is illogical)
C=> 1. meaning issue-structure helps explaining scientist not their thinking. 2. "they" is incorrect
D=> 1. meaning issue-structure helps explaining scientist not their thinking 2. SVA error
E=> ok "with its ....ommatidia" is a noun modifier and is referring to insect eye (closest noun)

A having hundreds of miniature eyes called ommatidia, help explain why scientists have assumed that it
This choice has a modifier error. Moreover, the verb help does not agree in number with the subject “the intricate structure…”.

B having hundreds of miniature eyes that are called ommatidia, helps explain why scientists have assumed that they
Although this choice corrects the SV error, the modifier error still is present.

C with its hundreds of miniature eyes that are called ommatidia, helps explain scientists' assuming that they
This choice corrects the modifier and SV errors, but it introduces a new one. The possessive apostrophe changes the meaning. Furthermore, it would be more correct to say scientists’ assumption rather than scientists’ assuming.

D with its hundreds of miniature eyes called ommatidia, help explain scientists' assuming that it
Corrects modifier error, but SV error is still present.

E with its hundreds of miniature eyes called ommatidia, helps explain why scientists have assumed that it
Corrects modifier and SV errors.

OG13 Question 7:

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

Hi,

I understand that Option A and B is wrong because of " having hundreds of..", an ING clause modifier and therefore, it modify the main subject, not the noun proceeding it. SO, if we change ", having..." to "having...", will it solve the modifier problem here? Thanks for your help in advance.

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

The subject of the question "The intricate Structure " is singular and as such SINGULAR verb should come .
ignoring the modifier "having .......ommatidia" , HELPS should come. Therefore. eliminating options- A and D
Similarly when one checks vertically , there is another subject verb agreement error after assumed- IT should be there - hence eliminating options
B and C. E is the correct answer resolving both the highlighted issues

Kindly revert in case i am wrong in my reasoning

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.

Tip: having hundreds.....ommatidia is modifying intricate structure nit insect eye--this is wrong. The sentence expects to modify insect eye

A having hundreds of miniature eyes called ommatidia, help explain why scientists have assumed that it-- as explained in tip; Sub-Verb-Agreement issue
B having hundreds of miniature eyes that are called ommatidia, helps explain why scientists have assumed that they--as explained in tip; THEY is wrong. It seems like scientists have evolved
C with its hundreds of miniature eyes that are called ommatidia, helps explain scientists' assuming that they--THEY has no clear antecedant
D with its hundreds of miniature eyes called ommatidia, help explain scientists' assuming that it--Sub-Verb-Agreement issue
E with its hundreds of miniature eyes called ommatidia, helps explain why scientists have assumed that it--ok

in option C: with its hundreds of miniature eyes that are called ommatidia, helps explain scientists' assuming that they..

Lets assume that the bold\italic "they is correct and says "it", so S-v agree in number, but the underlined part "eyes that are called" is as it is. Would we have a redundant "that are"? It would be wordy, right? So a more correct way of writing it would be simply "eyes called" so -ed modifier following the noun it modifies.

Am I correct here?

Thank you!
