Critical Reasoning

Membership in the theta delta psi fraternity is easily obtained by those who have previously had strong social connections with the existing fraternity members before college. However, one must have attended high school with one or more of the members in the order to forge such strong social connections. People who lack these social connections because they have not attended high school with one or more current fraternity members will therefore find it difficult to join the fraternity.

This argument displays flawed reasoning because it neglects to consider the possibility that

A) many of those who went to high school with theta delta psi fraternity members did not themselves become members of the fraternity.
B)it is more important in the long run to socialise with non-fraternity members than to develop strong connections with fraternity members.
C) it is more difficult to forge social connectors with fraternity members than with non-fraternity members
D) one may easily obtain membership in the fraternity through means other than having strong social connections with existing fraternity members.
Some current members of the fraternity did not go to the high school with other members.

OA: D

QUERY: In the argument the author clearly states people will find it difficult to join the fraternity if they havent attended school together with fraternity member. How can the answer consider that there might be other easy ways? Is this not contradicting the argument?
