966 - Logical Reasoning

Question : Opponents of laws that require automobile drivers and passengers to wear seat belts argue that in a free society people have the right to take risks as long as the people do not harm others as a result of taking the risks. As a result, they conclude that it should be each person's decision whether or not to wear a seat belt.
Which of the following, if true, most seriously weakens the conclusion drawn above?

1. Many new cars are built with seat belts that automatically fasten when someone sits in the front seat.
2. Automobile insurance rates for all automobile owners are higher because of the need to pay for the increased injuries or deaths of people not wearing seat belts.
3. Passengers in airplanes are required to wear seat belts during takeoffs and landings.
4. The rate of automobile fatalities in states that do not have mandatory seat-belt laws is greater than the rate of fatalities in states that do have such laws.
5. In automobile accidents, a greater number of passengers who do not wear seat belts are injured than are passengers who do wear seat belts.
