Task: Question Answering
Input (English): passage: The set of integers, with the operation of addition, forms a group. It is an infinite cyclic group, because all integers can be written as a finite sum or difference of copies of the number 1. In this group, 1 and −1 are the only generators. Every infinite cyclic group is isomorphic to this group.
 question: can a cyclic group have more than one generator?
Output (English): Yes
