D.

Correct idiom here :X is a descendant "of" Y

"descended from" is also a correct idiom

"Therefore I should infer from analogy that probably all the organic beings which have ever lived on this earth have descended from some one primordial form, into which life was first breathed."

Subject, "the pattren", is singular that requires a singualr verb and that eliminates ABC.

Between D and E, they have 2 major difference:-

1. "may be" and "might be": Every one alive today - so needs "may". "Might" may also indicate past possibility but "may" only does so for present and future possibilities.

2. "descendant of" and "descendant from" - thats entirely about the correct idiom. "descendant of" is better than "decendent from".

But the verb "may/might" is the main reason that eliminates E and keeps D.

+1 D

"may" is prefered for present actions. "might" is usually used for past events.

Pattern is singular. So down to D and E.

Descendent of is the correct idiom. Hence eliminate E. We are left with D.

ABC are eliminated because of the indicate being singular between D and E , D is better because D has descendant of , we use a species mite have descended from , but we use descendant of.

great question! i picked D, which appears to be right.

Might vs May was my biggest take away here. I will have to learn more about Might (past) and May (future and present)

Thanks!

Difficult question!

A) "indicate" does not agree with "the pattern"
B) idem
C) "may indicate" changes the meaning
D) looks fine, let's go to the next
E) looks fine too, let's see what is different

process of choosing:
1) between "might" and "may", I would use "may" (but I don't know whether this is better... anyone know?)
2) my ear says that "descendant from" is awkward. If I would say "descendant from", it would be a country or something like that. However, this "descendant" sounds like "descendant of Japanese or sth like that.

Agree?

In this particular case: 'descendant' is an adjective and hence should be followed by 'of' whereas 'descended' is verb and hence should be followed by 'from'.

I dont think that in C "may" is the problem. singular things can have may also. "I may go to the party" "They may come to the party."

Usage of may/might is interchangable.

Coming back to the question. C is wrong because of the "who had". There is no series of events one after the other. "who had.." just modifies the woman and is not related to anything else written earlier in the sentence.

And C is also wrong because of the wrong placement of "may", which changes the original intent.
