It is C for the last one. According to an unofficial explanation, "might" is a legitimate substitute for "may". D is missing a preposition.

What preposition is missing in D?
The second Sc has confounded me . SOS .
Agreed the Sc 1 has nothing to do with may / might . But since the topic has been broached , could somebody explain when should we use may and when should we use might ?

Yep, might is the simple past tense of may. In this sentence, we need present tense. Hope that help

IMO D as clear use of Idiom. Also S-V agreement.

According to scientists at the University of California, the pattern of changes that have occurred in human DNA over the millennia indicate the possibility that everyone alive today might be descended from a single female ancestor who lived in Africa sometime between 140,000 and 280,000 years ago.


Just to confirm..
I believe the high lighted text would be the subject of the sentence? or is it just pattern of changes?
please justify!
And any specific grammar rule which tells us to avoid subjects that have a relative clause ( here That)

hi everybody dont you think that the pattern of changes that have occurred is wrong . Since the pattern of changes is singular ,it must be has occured right ?

(A) indicate the possibility that everyone alive today might be descended from a single female ancestor who
(B) indicate that everyone alive today might possibly be a descendant of a single female ancestor who had
(C) may indicate that everyone alive today has descended from a single female ancestor who had
(D) indicates that everyone alive today may be a descendant of a single female ancestor who
(E) indicates that everyone alive today might be a descendant from a single female ancestor who

I am stuck between D and E , i.e, between May and Might :?: ...Please explain!!


Can someone please explain why C is wrong?

Thanks :)

Answer: D

Eliminate A and B due to subject-verb agreement --> "The pattern of changes" --> requires plural "indicates"

Answer C changes the meaning of the sentence.

Between D and E --> idioms: descendant of vs. descended from, thus D is correct

Answer C changes the meaning of the original sentence.

The original sentence is saying that the pattern of changes DEFINITELY indicates a possibility that needs confirmation.
Answer choice C is saying that the pattern of changes MAY indicate a possibility that needs confirmation.

Thus, the two sentences differ in meaning.

No, it's a subordinate clause - just not contained within two commas.

You can rewrite the sentence as: "The pattern of changes, which have occurred in human DNA over the millennia, indicates the possibility..."
