If p and q are positive integers, what is the value of q?

(1) \(q^{p-1} = 1\) --> if \(p=1\) then \(q^{p-1}=q^0=1\), which means that \(q\) could be ANY positive integer. Not sufficient.

(2) \(p = 1\). Clearly insufficient as no info about \(q\).

(1)+(2) Nothing new: \(p=1\) so \(q^{p-1}=q^0=1\), which means that \(q\) could be ANY positive integer. Not sufficient.

Answer: E.
