Several ancient Greek texts provide accounts of people being poisoned by honey that texts suggest was made from the nectar of rhododendron or oleander plants. Honey made from such nectar can cause the effects the texts describe, but only if eaten fresh, since the honey loses its toxicity within a few weeks of being made. In Greece, rhododendrons and oleander bloom only in springtime, when they are the predominant sources of nectar.

Which of the following, if true, most strongly support the accounts of Greek texts?

Jane: Television programs and movies that depict violence among teenagers are extremely popular. Given how influential these media are, we have good reason to believe that these depictions cause young people to engage in violent behavior. Hence, depictions of violence among teenagers should be prohibited from movies and television programs, if only in those programs and movies promoted to young audiences.

Which one of the following, if true, most strengthens Jane's argument?

Vorland's government is planning a nationwide ban on smoking in restaurants. The objection that the ban would reduce restaurants' revenues is ill founded. Several towns in Vorland enacted restaurant smoking restrictions five years ago.

The amount collected in restaurant meal taxes closely reflects restaurants' revenues.

Which of the following, if true, most undermines the defense of the government's plan?
