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?

There are no plants that Greece in ancient times that produce more nectar than rhododendrons or oleanders does.
In areas where neither rhododendrons nor oleanders grow, honey is never poisonous.
A beebive’s honeycomb cannot have some sections that contain toxic honey and other sections that contain nontoxic honey
The incidents of honey poisoning that are related in the ancient texts occurred in the springtime or in the early summer
Whether the honey in a beehive is toxic depends solely on which plants were the source of that was used to make the honey.

答案是D，我想问B为什么不行。
“在没有rhododendron or oleander的地方，蜂蜜就无毒”不也是加强了结论么？
