Answer:
Forth one and I'm sorry if my answer is going to turn out to be wrong.
Explanation:
This question is missing the options. I've found the complete question online. It is the following:
Which of the following statements is the inverse of "If you do not understand geometry, then you do not know how to reason deductively."?
A. If you reason deductively, then you understand geometry.
B. If you do not reason deductively, then you understand geometry.
C. If you understand geometry, then you reason deductively.
Answer:
The inverse of that statement is:
C. If you understand geometry, then you reason deductively.
Explanation:
To determine the inverse of a statement, we must negate both the hypothesis and the conclusion. In this case, the hypothesis is "if you do not understand geometry." It is already a negative sentence, which means its negation is "if you understand geometry." The same goes for the conclusion "then you do not know how to reason deductively." Its negation is "then you [know how to ] reason deductively." Putting them together, we have "If you understand geometry, then you reason deductively." - letter C
I say the answer to this is B. It leaves the impression of an unambiguous happy ending
