Hello, this is the question:

T won’t be selected unless S is selected.

it must be true that...

My answer : - T → - S

The correct answer: T → S

I am really confused on this question because if T won't be selected unless S is selected, shouldn't that mean IF T is not selected THEN S was not selected, I am confused on how to distinguish between the two options.

Thank you so much
