I initially had the same thought but then realize had this section is at the beginning of the RC section, I'd not pay less attention to it than I 'd after done this many lessons and drills.

They should put this section at the beginning of the module.

I got 5/5 on the first try then change three of them in blind review.....

If your answers are incorrect, then I will correct it. Inc→C, contrapositve that, /C→/Inc,

If I don't correct any of your answer, then they are correct.

I don't correct any of them, therefore they are correct.
