How many pairs (q, q+1) have one or more prime factors common, where q is an integer and 2 ≤ q ≤9 ?	Choose the correct choice from the following options:
A) 0	B) 1	C) 2	D) 3	E) 4
q and q+1 are consecutive integers.   Two consecutive integers are co-prime, which means that they don't share ANY common factor but 1. For example 20 and 21 are consecutive integers, thus only common factor they share is 1.   0nswer: 0.
