If a number p is prime, and 2p+4 = q, where q is also prime, then the decimal expansion of 1/q will produce a decimal with q-1 digits. If this method produces a decimal with 166 digits, what is the units digit of the product of p and q?	Answers:
A) 1	B) 3	C) 5	D) 7	E) 9
1/6 = 0.1666666... (a repeating pattern one digit long)   1
