Hi All,

Since the subject is "pattern" (singular) why do we have to discard "may" ?
Don't we say : "He may come later" or "He may visit us next week" ?(same orthography as answer choice C)

Also, some argue that "may indicate" change the meaning, but since may indicate the possibility of something

Why do we consider "may indicate that" to have a different meaning from "indicate the possibility that" ?

As I am not native speaker, my question could seem irrelevant and I apologie for that,

C is incorrect not because of wrong S-V agreement ("may indicate" is alright), but because of unnecessary use of past perfect ("HAD lived" is not required).

Your reasoning is valid - "may indicate" and " indicate the possibility" both convey the same meaning.

The problem in A is the redundancy due to simultaneous use of "possibility" and "might".

...the possibility that everyone alive today might be descended... correct
...the possibility that everyone alive today might be descended... redundant

The same problem is there in B as well:"might possibly"

Why is not there "had" at the end of the phrase in D? That bothered me to such an extent I chose B.

Past perfect is to be used only when it is required to highlight the sequence of events. If the sequence is clear, then simple past is preferred. Following is an excerpt from Manhattan SC guide:

Do not use the perfect tenses when the simple tenses will do. The GMAT prefers simplicity.
Wrong: Joe LEARNED about an epoch in which dinosaurs HAD WALKED the earth.
Right: Joe LEARNED about an epoch in which dinosaurs WALKED the earth.
In the first example, the Past Perfect had walked is unnecessary. Although the action had walked does take place earlier than the action learned, the earlier action does not have a direct bearing on the context of the later action. The sequence of time does not need to be clarified or emphasized. Thus, the Past Perfect is considered wrong in this context.
