In the subset {3, 7} of A = {2, 3, 5, 7}, which elements are taken from A?
Answer and explanation
Correct answer: Both 3 and 7
The subset {3, 7} is formed by selecting the elements 3 and 7 from the original set A = {2, 3, 5, 7}. Both selected numbers appear in A, so {3, 7} is indeed a subset of A. The elements 2 and 5 are not selected in this particular subset, but their absence does not affect the subset relationship. Therefore both 3 and 7 are taken from A.
