Question

Which of the following statements is logically equivalent to "If I study, then I get better grades"? If I do not study, then I do not get better grades. If I get better grades, then I study. If I do not get better grades, then I do not study. If I get better grades, then I do not study.

Answer 1

It would go along with, "if I get better grades, then I study."

Answer 2

I would think that the correct answer is the 1st one: If I do not study, then I do not get a better grade. 

I think this would be correct because it's basically the same as the sentence they give you! For a better understanding of this, go to:   https://en.wikipedia.org/wiki/Logical_equivalence
