Determine whether the following disputes are verbal, factual, or some combination of the two. If verbal, discuss whether the dispute arises from vagueness or ambiguity.
BRIAN: That new morning-after pill, RU-486, causes abortion. Therefore, since abortion is wrong, you should never take that pill.
ELAINE: How ignorant you are! RU-486 merely prevents implantation of the fertilized ovum. Therefore, since the woman never gets pregnant, there is no abortion. 18.
PENNY: In my mind, the use of marijuana should be legalized. After all, caffeine and alcohol are no less of a drug than marijuana, and it's not illegal to enjoy a glass of beer or drink a cup of coffee.
SAM: Your conclusion is way off. Beer and coffee are not drugs; they're foods.
