We have to choose which set of integers is included in (-1, 3 ]. Integers that are included in this set are: 0, 1, 2, 3. Set number 2 is not included because - 1 is not among those integers. Set number 3 is not included because it has numbers - 1 and 4. Set number 4 is not included because numbers - 2 and - 1 are not in the interval ( - 1. 3]. Answer: (1) { 0, 1, 2, 3 }.
