PT4.S1.Q10 - Rhizobium bacteria living in the roots of bean plants and other legumes...

The question stem says, "The argument above makes which one of the following assumptions?"

This was labeled a Necessary Assumption question.

Wondering how to tell when a question is NA/SA when it doesn't explicitly say in the question stem? Or maybe I am just missing something in the question stem?

this one is definitely a more toned-down NA question stem, but SA/PSA questions typically have some combination of the words "would allow the conclusion to be properly drawn" or "justify the conclusion" or "if valid, would..." (PSA).

also, for NA questions, they're asking you what the assumption the argument is already making in order to survive. SA questions are different because they ask what assumption would strengthen the argument/make it valid.

@kilgoretrout

This was a really great explanation. Thank you so much.

So now I when I encounter some toned down assumption question, this is probably going to be an NA question.
