This one I was lost on... any lead would be good!

Saw the 3-2 split and chose the wrong pair entirely.... who can modify tribes? I thought thats' only for persons?

Furthermore, isn't amongst better for groups... why is it not B then?

Thanks in advance!

C is better cos the idiom it interact with

Among is comparing more than 2

Between is when we compare two things

E can be rules out for not using the correct idiom ...

[sujaysolanki]

As for the second sentence
the second part of the sentence ...signifies the present ...the discovery
Hence the first part requires teh past tense so we have D and E

In E the it is ambiguous ..pronuon reference error

[hemanth28]

for the first question b/w option C and E,option E lacks parallalism so E is wrong.

Who can be used for tribes, because tribes are groups of people. As for B, the idiom is interact with, not interact among.
