Is there a video for this question? There is no S & N relationship in this question, correct? B is just correct because it restates the "some" relationship from the second group of environmentalists?

@OQ There is not video yet.
You're right. This is a quantifier question, so the relationships are going to be in terms of "some," "most," or "all."
(B) is correct for a few reasons. It recognizes that "many environmentalists" can only definitively be interpreted as "some" (which is why (C) is wrong). It also recognizes that holding non economic reasons does not mean that those are the only reasons they hold (which is why (D) is wrong). (A) and (E) also overstate the argument in the question by making the implications broader than can logically be concluded from the information given.
