Answer 1

Assertion: 2 is a rational number.: CORRECT, because we can write 2 as 21, where both 2 and 1 are integers. Reason: The square roots of all positive integers are irrationals.: INCORRECT, because square roots of perfect square positive integers are themselves integers, not irrational. e.g. √4=2.
