I hope I dont get a question like this on the LSAT haha

Yikes.. this one got me... most of the answers are pretty good answers haha

This doesnt make sense to me...

If this says that: Blackouts WILL occur UNLESS the heat wave abates.. Then how does it make sense to say: If the heat wave doesnt abate, then blackouts will occur?

Wouldnt it be: If the heatwave doesnt abate, then blackouts wont occur?
