Answer 2

{1, 2, 4, 5, 10, 20}

Answer 3

The set N represents the set of natural numbers that are factors of 20. This means that all the numbers in the set N are whole numbers that can divide evenly into 20.

The correct selection in roster form is {1, 2, 4, 5, 10, 20}.

This is because:
- 1 is a factor of 20, as it can evenly divide 20.
- 2 is a factor of 20, as it can evenly divide 20.
- 4 is a factor of 20, as it can evenly divide 20.
- 5 is a factor of 20, as it can evenly divide 20.
- 10 is a factor of 20, as it can evenly divide 20.
- 20 is a factor of 20, as it can evenly divide itself.

Therefore, the set in roster form is {1, 2, 4, 5, 10, 20}.
