1. I think C.
"She's never tried harder" means that Paula made her best this semester. In other words "there was no time when Paula worked harder than this semester"

2. I think C.
The man implies that air-conditioner works only when they don't need it. It's like when you need a bus there is no one and when you don't need it , it goes every 5 minutes.
