My two cents regarding elimination of E:
E is wrong because it’s not really telling us anything about the Economist’s flawed assumption that making decisions -> public official. Just because two groups are cooperating doesn’t mean they’re different or the same. In fact, this answer choice can go either way of strengthening or weakening the
conclusion depending on how you choose to see it (see below for potential perspectives), but ultimately it does nothing to strengthen or weaken the
reasoning, which is also important to consider when considering the answer choices.
One way to strengthen the conclusion: we can assume that by cooperating, business executives are sharing some of the responsibilities of public officials, which strengthens the relationship between the two.
One way to weaken the conclusion: we can assume that by cooperating, business executives and public officials are working together as separate groups, which weakens the relationship between the two
