I got this one correct; however, I want to know why I got it correct.
Should you diagram the logic out for this stimulus? Basically, how I diagrammed it was like this:
RFCS OR LH ----> RFHS
NOT RFCS ---> HH
Contrapositive: NOT RFHS ----> NOT RFCS AND NOT LH
Contrapositive: NOT HH ---> RFCS
Answer Choice A: NOT RFCS ---> NOT NC AND NOT LH
Contrapositive: NC OR LH ---> RFCS
None of these match the stimulus so Answer Choice "A" is out.
Answer Choice C: NOT RFCS ---> NOT LH AND RFHS
Contrapositive: LH OR NOT RFHS ---> RFCS
None of these match the stimulus so Answer Choice "C" is out.
Answer Choice D: NOT RFHS AND NOT RFCS ---> LH AND HH
Contrapositive: NOT LH AND NOT HH ---> RFHS OR RFCS
None of these match the stimulus so Answer Choice "D" is out.
Answer Choice E: RFCS AND RFHS ---> LH AND NOT HH
Contrapositive: NOT LH OR HH ---> NOT RFCS OR NOT RFHS
None of these match the stimulus so Answer Choice "E" is out.
Answer Choice B: NOT RFCS ---> HH
This is the contrapositive in our diagram, thus making Answer Choice B correct.
Is the logic here correct?
