false. Bi-conditional statements are equivalent to a=b.

a=felipe is a swimmer

b=felipe is an athlete

If Felipe is a runner, he is an athlete, but not a swimmer. Therefore, the statement is false.

Another way to explain...

Bi-conditional

a->b && b->a

a->b

If felipe is a swimmer, then he is an athlete. Statement is true.

If felipe is an athlete, next he is a swimmer. Statement is false.

T && F

False
