Determine whether each of the following arguments provides adequate support, or any support, for its conclusion. Explain why.
1. I shouldn't get a speeding ticket for going fifty-six miles per hour, because my driving did not all of a sudden get more dangerous when I passed the speed limit of fifty-five.
2. No student should ever be allowed to ask a question during a lecture, because once one student asks a question, then another one wants to ask a question, and pretty soon the teacher doesn't have any time left to lecture.
3. Pornography shouldn't be illegal, because you can't draw a line between pornography and erotic art.
4. Marijuana should be legal, because it is no more dangerous than alcohol or nicotine.
(continued)
5. Marijuana should be illegal, because people who try marijuana are likely to go on to try hashish, and then snorting cocaine, and then freebasing cocaine or shooting heroin.
6. The government should not put any new restrictions on free trade, because once they place some restrictions, they will place more and more until foreign trade is so limited that our own economy will suffer.
7. Governments should never bargain with any terrorist. Once they do, they will have to bargain with every other terrorist who comes along.
8. If assault weapons are banned, Congress will ban handguns next, and then rifles. Eventually, hunters will not be able to hunt, and law-abiding citizens will have no way to defend themselves against criminals.
