Anybody wants to shed some light on the LAWGIC aspect of this question?

Apparently, according to PowerScore explanation, the stimulus is a bi-conditional relationship because of the phrase "if it satisfies two requirements".

Therefore, the bi-conditional relationship is as follows:

Accurately Describes using a few elements AND Make Definite Predictions (---) Good theory.

Would the contrapositive of above become:

/Good theory (---) /Accurately Describes using a few elements OR /Make Definite Predictions?

    Yes, you typed it the correct way.

    When there are multiple pieces to one side of a bi-conditional, I generally picture that whole set in parentheses and negate it.

    For instance, this statement:

    ( A + B ) (--) C

    ... would have this contrapositive:

    /C (--) /( A + B )

    ... which translates to:

    /C (--) /A or /B

    (you always switch AND to OR, and vice versa, when determining the contrapositive using this method).

    Hope that helps!
