I was reading the explanation of the "No" group 4 rule for the myths question from Kevin.

During the explanation, Kevin says if we use the "no" negate necessary rule, we must allow unless to negate the idea to which it is attached, i.e. containing truths.

My question is, is there an earlier lesson where we know that unless equals negation outside of our application of "unless" as a function outside of the translation for negate sufficient, group 3? I'm not sure where our earlier basis is for this.

I really like these!! I appreciated the bit in the Foundations section. I think scattering them in LR and LG (until August) would be great. They are motivating and make me feel warm and fuzzy!

5/5 (on medium), and I am proud of the time I took with BR to make sure I had solid reasons for the answers I chose. Now, to review all of LR and the drills on hard/hardest for more practice!

This whole section is going to cause me to throw my laptop out the window. I have gotten nearly every drill wrong!!!!

I'm going to piggyback on this reply. I was stuck between B and E, and on blind review and the drill, I picked E, too. I'm still not confident how it's wrong.

This is a technical issue, but when I try and change the difficulty level, it doesn't actually change the question difficulty. For example, I have tried multiple times to toggle to "hardest", and each time a drill generates, it still creates an "easiest drill". It won't even make "medium" drills despite that being the default. Any advice on troubleshooting?

Take a look at the section previous "Negating 'Some' Statements. It goes through how the negation of 'some' is 'all'. It's also discussed in the "Negating 'All' Statements" lesson.
