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.
