Happy bday !!

Great example of a conditional logic question here. I first tried think through it using normal peson logic then I switched on my LSAT brain (first question of the day) You can try to figure it out and think through what makes sense to you, but if you look at the logic only, it is very straightforward. I figured this out the second time. The question says

SFP -> /happy

just take the contrapositive because that we can guarentee is correct/we can infer.

happy -> /SFP.

Easy when you think about it like that.
