Having Weak Ties (I

Having weak ties (i.e., being merely acquaintances) with people from diverse networks can be more valuable than having strong ties (i.e., having close friendships) with people in similar networks. Why is this so?

A) Strong ties tend to be different from us, and different people tend to have different information and connections that we don't have.
B) Weak ties are acquaintances who are usually different from us and therefore offer resources we do not possess.
C) Strong ties are acquaintances who are usually different from us and therefore offer resources we do not possess.
D) Weak ties tend to be similar to us and to each other, and similar people tend to have the same information and connections that we already have.
E) Strong ties serve as a "bridge" across several unrelated networks, where we receive unique resources from each network rather than more of the same resources.
