@SusanLeifker October!

@yes-coconuts Same! I will take it as a win!

@MM_xoxo Glad I am not the only one thinking this! Lol

How do I know when to take a contropositive on these? I thought it was pretty straight forward with sufficient, though it is necessary.

Anyone else originally select the right answer, then second-guess themselves and switch to a different one on these in particular? What is a good way to get rid of these? Most other questions I feel reasonably confident about.

My first 5/5! These one's seemed much easier but I will not complain.

I have always hated these types of questions. The chains have always brought me down (see what I did there?). Tonight, I can happily say that I actually got this one right, after spending about 9 minutes and 30 seconds on it. I graphed it all out and just went through graphing the answers out, and it was right infront of me. Don't ever give up! You've got this, and you should be proud of yourself for even trying! :) Good luck!

@MarcosGuzman415 same for me! I'll take it haha!
