Current legislation that requires designated sections for smokers and nonsmokers on the premises of privately owned businesses is an intrusion into the private sector that cannot be justified. The fact that studies indicate that nonsmokers might be harmed by inhaling the smoke from others’ cigarettes is not the main issue. Rather, the main issue concerns the government’s violation of the right of private businesses to determine their own policies and rules. Which one of the following is a principle that, if accepted, could enable the conclusion to be properly drawn

B. The right of individuals to breathe safe air supersedes the right of businesses to be free from government intrusion.
C. The right of businesses to self-determination overrides whatever right or duty the government may have to protect the individual.

During a single hour, an automatic camera photographed 100 vehicles that were speeding on a one-way road, and police a mile farther down the road photographed 49 vehicles that were speeding.

B. Drivers who are not exceeding the speed limit are less likely than drivers who are speeding to reduce their driving speed when they see a marked police car.

D. More than 100 vehicles passed the automatic camera during the hour in which the automatic camera photographed 100 speeding vehicles.
E. Not more than 100 vehicles drove past the police during the hour in which the police photographed 49 speeding vehicles.
