Don't capsule medications sometimes have liquid in them? I was thinking about Advil capsules and thought that you would need Advil to be in a liquid form to make the capsule. I have no knowledge of capsule medicines, but this is my thought process which led me to A. I can see that B is still a better answer choice though.

I chose A instead of B because in the stimulus there seems to be relevance between conclusion and premise, that is, driving. A maintains this relevance with health, but B's premises are completely arbitrary to the conclusion.

I think that C clarifies an ambiguity of "no more exercise".

Among other interpretations, the stimulus allows for a situation in which those who wear toning shoes exercise 6 hours per week and those who do not wear toning shoes exercise 6 hours a week.

C further defines what sort of exercise is done within those 6 hours, that is, those who wear toning shoes walk more. We would, therefore, expect the major leg muscles to be stronger for those who wear toning shoes.

I mapped the first sentence much differently than Kevin and I am still confused on how it is wrong. I took the first clause as /reduce biodiversity -> increase agricultural production which, I am pretty sure, is equivalent to how Kevin took it. The conjunction, however, is where I am lost. I thought that "but" is to be translated as "and" in conditional logic so I translated: /reduce biodiversity -> increase agricultural production AND abandon conventional agriculture.

Can someone explain why I am wrong?

@Bigsby Same here. I do not understand why "A" is properly drawn when it does not cover the next year. A feels limited in scope, but, admittedly, it is the best answer choice.

I am confused as to why I can't just use conditional logic for this question.

I am having a hard time distinguishing between when would be a good time to diagram and when not. The Diagramming for this question took me past the time limit when I probably could have gotten the answer correct without the diagram. Is there a way to recognize when to use a diagram and when not?

I chose A because doesn't A have to be true? If the Archaeologists are analyzing plant remains, then doesn't that imply they are able to analyze them in such a way that would prove your hypothesis? Can someone explain why this thinking is wrong?

I am confused why I am not to include physically dangerous. I thought Rev-> H and PD-> T. In the previous lesson, we had two separate conditionals combined. If in NYC, 10 building apartment, open and notorious, and another I can't remember. Even though two constituent parts of the sufficient condition were from a sufficient condition which started with "all" and the other two with "if". So we had in that instance a case in which we combined two separate sufficient conditionals but here we do not.

Three seems to be withholding another element. I thought that it would be inf -> produce antibodies and fight. The purpose clause would be analogous to the "with..." clause in question two. I see my mistake, that in the sufficient condition, I should have included after a week, but if we care about including all elements of consequence, then shouldn't we also include the purpose clause? I feel that we haven't covered such a situation and there is an active disregarding of my problem. Am I mistaken, or is there a good reason the purpose clause is not included?

A little tripped up on "whenever" as a sufficient condition indicator. I can memorize "only when" is a necessary condition indicator and "whenever" is a sufficient condition indicator, but I am confused. Does the generalizing temporal force of "whenever" make it a sufficient condition, and does the constricting temporal force of "only when" make it a necessary condition?

@amytorres I did the same thing. I did not respect the force of "they had been accustomed to maintain"
