Amazing Explanation E-gmat but even in E, we have 3 things :shock:

.. whereas you mentioned that either .. or.. must have only 2 things . E looks like either X,Y or Y.. Or is it that Y is modifying X? Please help. Regards, Sach

egmat · Answer

Hi Sachin, Well choice E reads: to find and attack prey, to defend themselves, or to communicate and navigate. This choice does not have "either". In this choice, the three entities are joined by "or". Hope this helps.

Thanks. Shraddha

Parallelism wins.
The only choice that provides paralleism is choice E. To attack, to defend, to communicate
