Few of my friends spent the last weekend in a resort, which was offering inter alia the following activities:
Tennis, swimming, chess and disco.
Each one of my friends participated in two of the above, and every subset consisting of two activities was chosen by one of my buddies.

What number could replace the word "Few" without affecting the truthfulness of my story?

There are six ways to create a subset consisting of choices of exactly two activities out of four offered (where order of choice not significant).  So, I'll reply SIX.  Somehow this appears too obvious to be an answer,  so I'll anticipate other analysis.
