its a tricky question .. u need to understand the usage of among ...



among each other -- wrong
with one another -- correct

among themselves -- correct

between is used for two
among three or more

and Interact with is an idiom..

hope its clear now ...

Here is my take:

'Among' is used for a group. For example, Thieves gave half of the loot to police, and distributed rest of it among each other .

In option B, "tribes who interacted among each other" is correct - here interaction is happening within the group. While the second use of 'among' is wrong - here one tribe is interacting with other tribes, outside the group.

Lets say, Option C is not present...

Is there any other option , which still can be the answer?

C it is.

The soln hinges on knowing this key usage:

1. Interaction between TWO groups, u use "each other"
2. Interaction between MORE THAN TWO groups, u use " one another".


once this is identified, one can easily zone in as hawk and swoop the
prey (C) .

Red part is incorrect....

I guess by red you meant among .

Interaction among MORE THAN TWO groups, use " one another".


Learned something good.

Thanks
