Answer 1

Prime numbers

Explanation:

Consider that a prime number is a number with only two factors: 1 and itself (Example: {2, 3, 5, 7, ...}). Also, state that 2 is the only even prime number.

The set of all even numbers within the set of prime numbers can be described as {2}. Therefore, the universal set is all prime numbers itself.
