These questions have me internally screaming.

@Anibal C Perez This is a great explanation! Thank you

@daniel.abdulian This is where I am now - I was doing SO WELL for so many of the "you try" questions and now I've gotten the last four wrong and I'm spiraling - I feel like I can't even think straight anymore. I'm backing away from the computer now lol.

I keep confusing sufficiency and necessity in these questions.... and his explanation makes complete sense when I hear it but when I'm going through the questions myself I just keep making the same mistake. Any tips on how I can catch myself on this?

@tero230524 I made the same mistake - I understood both the word "disappear" and the word "eradicated" to mean that the disease was gone completely.... oops.
