For the actual format of the feedback I'm a bit confused. Under Lawgic is it the correct translation and then the contrapositive underneath or are both responses correct?

Doubted myself on BR, shaking my fist at the sky like an old man

James really sounds like he's worried about his job, yikes dude

totally missed that the prehistoric creature was a reptile and not also a mammal, that's what I get for reading fast

5/5 lets go lesson 2 (narrator: this has never happened before and may never happen again)

I know it's been 100+ lessons but this is probably the first time the sufficiency necessity clicked

Almost picked A on BR but wanted to stick to my guns, should have let myself fold

#feedback I like the highlighted stimulus analysis under the question, very helpful!

Got it right on first try and then wrong on BR, should I be taking it more seriously if I change it during BR? It's only cause I thought it could be another answer.
