#help I dont understand how politicians are members of the elite is something we can imply from Q5....

Can someone please explain the reason why we can contrapose one of the rules but not the other? This is really not clicking for me...I need it in more digestible terms lol

#help. Doesn't answer D, if negated, destroy the argument? "No substances of medicinal value contained in rain forest plant species will eventually be discovered if those species are studied." Essentially saying that even if the species are studied, we won't get medicinal value from them. Which basically renders the argument null bc if we don't have the rain forests, who cares because the plants wouldn't have any medicinal value anyways?

I'm not sure if I'm negating the answer wrong or if I'm just misunderstanding it. But I definitely am lost. #help

How do you know where to draw an intersection between terms in the conditionals? #help

Confused on E. Wouldn't the fact that short term methods use more skills vs long term methods move the experiment further away from the "ideal experiment?" In this case, the time isn't the reason for the success, its the fact that different techniques are being employed.... making the argument weaker. What am I missing? #help
