This helped me a lot with breaking down these types of questions, they were overwhelming me before. I am also sure the foundations lesson helped me in understanding the piecemaker strategy as well.

#feedback, I love the form of questions followed by practice to apply what you have learned!

I could be wrong, but working through this diagram actually just helped click finally the difference between subsets and supersets for me. Essentially, necessary conditions are like supersets that subsets or sufficient conditions live within. Conditons are essentially relationships so understanding the subset vs. superset through a diagram is very relevant I think. For the second example I believe since we are demonstrating a necessary condition a.k.a group 2 then: Yoda training would be the bigger circle (the necessary condition) and luke is a jedi would be in a bubble within this condition, living within. Articulated, this is because yoda can train without luke, but luke cannot be a jedi without yoda's training. this would be the opposite for the first example demonstrated visually I think. Correct me if i'm wrong but this is how I have come to understand it. The equations can be a little hard for me to wrap my head around, so sometimes speaking and drawing it out helps it become more applicable!

To me it makes the most sense to decide what the rule is literally and the exception. The other methods over-complicate it for me. For the first two examples, I've done so far I have instantly known the rule and exception. However, should I try to learn the other methods in case things get more complicated. I don't want to overthink and confuse myself, if this is working for me unless people think this won't work consistently? #help
