Question

Reason abstractly.

Given: (1) If X is blue, then Y is gold.
(2) Y is not gold.
Which of the following must be true?
A. Y is blue.
B. Y is not blue.
C. X is not blue.
D. X is gold.

Answer 1

C. X is not blue.

Explanation:

Hi there!

We're given that if X is blue, then Y is gold, but Y is not gold.

Therefore, there is no way that X is blue, because if it was, then Y would be gold. But it's not, so X is not blue.

I hope this helps!
