A. have been shown to be closely related to the DNA of some modern, indigenous East Asian populations and therefore are ---- The DNA is singular. ‘Have been’ is the wrong verb

B. has been shown as closely related to the DNA of some modern, indigenous East Asian populations and therefore - has bee is ok but we need a verb after therefore to make the sentence parallel; or else it is just a fragment.


C. have been shown it is closely related to the DNA of some modern, indigenous East Asian populations and therefore are – ‘have been’ is wrong

D. have been shown as being closely related to the DNA of some modern, indigenous East Asian populations and therefore -- 'have been' is wrong

E. has been shown to be closely related to the DNA of some modern, indigenous East Asian populations and therefore is --- ‘The correct choice’

This sentence can be solved mechanically. What is the main issues here? The subject "The DNA" is singular— the sentence is tricking us to think two women are the subject of the sentence; prepositional nouns can never be the main subject— but the verb "have" and "are" are in plural form. They should be corrected to "has" and "is"

Quote:
A. have been shown to be closely related to the DNA of some modern, indigenous East Asian populations and therefore are

A's error is discussed above.
Quote:
B. has been shown as closely related to the DNA of some modern, indigenous East Asian populations and therefore

This corrects "have" to has. Let's keep it.

Quote:
C. have been shown it is closely related to the DNA of some modern, indigenous East Asian populations and therefore are

Same as A. C is out.
Quote:
D. have been shown as being closely related to the DNA of some modern, indigenous East Asian populations and therefore

Same as A. D is out.

Quote:
E. has been shown to be closely related to the DNA of some modern, indigenous East Asian populations and therefore is


Both verbs are corrected as discussed. Keep E.

What is the different between B and E? The verb for the second part "IS".

Can B omit the word "is"? Let's check the verb on the other side of the sentence, "has been shown". Plug this to the second part of the sentence: " The DNA therefore has been shown a sign". This does not make any sense. So E is the correct answer.

OFFICIAL EXPLANATION

Though "women" is plural, the actual subject of our sentence is "DNA," which is singular, so we need the verb "to have" to be in singular form.
Only (B) and (E) use "has," meaning that we can eliminate (A), (C), and (D). The primary difference between our two remaining options is whether the DNA has been "shown as closely related" in (B) or "shown to be closely related" in (E). In English, the idiomatic phrasing is "shown to be closely related," making (E) our answer.

The correct answer is Choice (E).
