Answer 1

The correct evaluation of the argument is "valid but unsound."

The argument is valid because if the premises were true, the conclusion would logically follow. However, the second premise is not true (not all feathered creatures can fly, e.g., ostriches and penguins), which makes the overall argument unsound.
