原文：
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?
　　A. There are no plants that Greece in ancient times that produce more
nectarthan rhododendrons or oleanders does.
　　B. In areas where neither rhododendrons no roleanders grow, honey is never
poisonous.
　　C. A beebive’s honeycomb cannot have some sections that contain toxic honey
and other sections that contain nontoxichoney
　　D. The incidents ofhoney poisoning that are related in the ancient texts
occurred in the springtime or in the early summer
　　E. 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,可是B不正是无因无果型加强吗?大神们帮忙解释下吧

题目问的是哪个答案最能强烈支持text的描述,
A 没有提到有没有植物比杜鹃或夹竹桃产花蜜更多
B 在两种植物都不种的地方,蜂蜜不一定就没毒（有可能蜜蜂飞到长有杜鹃或夹竹桃的地方采蜜,或者花蜜被从其他地方运来）
C 蜂巢里面可以有些区域有有毒花蜜,有些没有,取决于蜜蜂从哪采蜜
D 文中提到杜鹃或夹竹桃春天开花,所以发生中毒应该就在春天；最晚到early summer（再晚毒素就失效了）
E 花蜜有无毒不仅取决在哪些植物上采蜜,也取决于放置的时间


B是无因无果型加强.不是很明白你的意思
