Can Someone explain the difference between answer choices B and E

I'd also like to know the difference between B and E, please.

I had the same question, and I was able to solve it by diagramming the answer choices, because both of them have S&N language, so I diagrammed them and saw which one is more accurate according to the passage given.

Sufficient -> Necessary B: Vote -> Benefit All Residents E: Benefit All Residents -> Vote Thus, for the purpose of the developer's argument, E is the right answer.
