There was one circular reasoning committed in this lesson

I had the exact same translation, which led me to choose E. I think this is one of those cases when relying solely on conditional indicators come back to bite you. The sentence has both negate necessary and necessary indicator in it, so if you simply rely on the indicators, you wouldn't know what to do since both indicate necessary condition. Once I read the E again, I instantly know what it is talking about "no sizable subgroup exists that will have their feet cured only if they don't take M" and that conditional statement does not touch the flaw of the stimulus.

I am having issues understanding D. Just because you eat out more, it doesn't necessarily mean that the dinner you DO eat at home will be on par with the nutritional level of those who spent 100 minutes more to prepare them at home. Am I tripping?

Finally got one SA question right! Don't be discouraged let's take one step at a time!

I do not understand the second example. If the conditional indicator is Only, that translates to logic Uses Force --> Jedi. Since Dooku uses the force, he triggered the sufficient and is a Jedi. This is a valid logic. But why did the text say I made up my own premise? If the conditional indicator is only, I did not make anything up did I? it's very confusing.

This is the truth. When two rows of lawgic are connected, some relationships can be found across most of the letters.
