Is it always the case that if an argument for a sufficient assumption question has descriptive premises with a normative conclusion (saying one should do something or ought to do it) then the answer choice must have normative language to close that gap?
Looking at PT 22, Section 4, Q13 and PT 62, Section 2, Q17, I can see many reasons to eliminate the other incorrect answer choices besides them lacking the normative language. However, I'm still hesitant to skip straight to the answer choices that say "should" because I'm still not sure if you need the word "should" or similar language to close the logical gap between the conclusion and premises. Is normative language in the answer choice always necessary to prove a normative conclusion when the premises don't have it?
Thanks!
