Huh?

From my understanding, you're never supposed to question the truth of the premises, only the truth of the conclusion. You can question, however, the gaps between the premises.

@Dean_Dyrmishi When you see Except, Until, and Without you can treat them as if you saw unless

@Edith yes, the original and contrapositive statements are the only valid inferences

@jayjamesa If and only if creates a double arrow/ bi-conditional

@LilyAsgari OHHHHHHHH i forgot about the order thank you!

@LilyAsgari I am confused, isn’t contrapositive the exact same as the original statement so why would it be wrong

Double it and give it to the next person

@TBlack05 I agree with biglaw4life. Since this is an SA question, you want to look for an answer choice that 100% makes it so the conclusion follows. Think about it in a conditional logic way: SA--> conclusion-->NA. The Sufficient assumption 100% of the time leads to the conclusion, and the Necessary assumption is what relies on the conclusion. Hence why SA answer choices are okay to be stronger than NA.

@akshayamadduru401 Not even joking exactly how I did it
