@BenBeecham I see this lesson as more of a tale of what a perfect casual relationship should have to be assumed to be true, and if any of these factors are missing, look for those as the flaw in the experiment.

I love how fun this curriculum is. Makes it that much easier to look forward to studying. Never get rid of this personality.

@A. Belle great explanation. I like this more than the "scoop" example 7sage has been using.

The 2nd Framework feels pretty intuitive. Again, love this curriculum. I can feel my brain expanding.

Makes sense! I think people struggling with this, need to understand that memorization shouldn't be the goal, but this should feel intuitive!

Of course, in a contrapositive, if either of the previously NECESSARY conditions fail, the sufficient cant happen, because both were required!

Just think about it logically. Don't make it more complicated than it has to be.

@CheyenneBandy So does JY mean it is always Subject ---> Predicate? If so this is really cool. Also a lightbulb moment for me

5/5! Awesome!

Great Question with tricky answers. Made me 2nd guess myself, but often I'm finding just building that intuition of the Sufficient --> Necessary chain is the most important. Just knowing how a condition is being treated, and being able to feel when the question swaps it from a sufficient to a necessary condition is helping a lot. Nothing substitutes practice and memorization!

Great Lesson! Easy to understand if you follow along yourself. Loving these lessons ngl

Great exercises! I feel that the individuals commenting about the level of difficulty did not spend enough time studying the previous lessons and memorizing the conditional indicators. Great Work! Genuinely. I feel I am improving a lot!

@athmar390 Thank you! I was initially removing the "Cannot" from the variable before negating, and the resulting sentence didn't make sense. But now I get it, don't remove "cannot" unless it is the conditional indicator separating two ideas, which it isn't. Makes sense thank you! So Group 3 rules would apply, identifying "Unless" as the conditional indicator.

/(One Cannot Become Jedi) ---> Possesses Discipline

Translates into

One CAN become Jedi ---> Possess Discipline

or

/Possess Discipline ----> (One Cannot Become Jedi)

Thank you!

YESSSS 5/5 I love this curriculum

If I am tall, then I will hit my head on door frames.

T ----> DF

If I do not hit my head on door frames, then I am not tall.

/DF -----> /T

Being Tall is Sufficient, as in it is enough, to then hit my head on door frames. If I am tall, it is necessary that I hit my head on door frames.

If I do not hit my head on door frames, it is Sufficient, as in it is enough to then say, I am not tall. Because it is necessary to NOT be tall if I am NOT hitting my head.

If one thing is necessary for a Sufficient thing, then not having that necessary thing means I cant possibly have the sufficient thing.

Contrapositive is basically saying, the Necessary item is NOT HAPPENING, so the Sufficient one cannot be true.

I woke up to the roof of my house missing. I look outside and my sister is inside of a large crane, looking at me and laughing. She is laughing in the way she does when she does something destructive. My sister took off the roof from my house.
