Exercise 7.1: #I -- Diagram the following arguments.

(a) If today is Saturday, then tomorrow is Sunday. If tomorrow is Sunday, then we'll be having pasta for dinner. If we'll be having pasta for dinner, then I should pick up some red wine today because in this state wine can be purchased only at liquor stores. and the liquor stores are closed on Sundays. Today is Saturday. Therefore, I should pick up some red wine today.

(b) Several States have abolished the insanity defense as a defense against criminal responsibility . This may be popular with voters. but it is morally indefensible . Insanity removes moral responsibility and, it is wrong to punish someone who is not morally responsible for his crime. Moreover it is pointless to punish the insane because punishment has no deterrent effect on a person who cannot appreciate the wrongfulness or criminality of his or her actions.
