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.
说的是如何增强他的解释
其实就是整个段落的解释没有完整和之前的strengthen不一样 strengthen是有结论有解释 你来增强他的结论 可以out of scope 这个整个解释过程都没有完整
段落上来先说的是结论 蜂蜜中毒是这两种花蜜
后面解释这两种花蜜是可以cause中毒 但是只有在新鲜的时候 这两种花是在春天成熟的 所以 我们要补充的解释内容就是 中毒发生的时间恰好就是他们bloom的时间从而增强结论 就是这两种plant 导致中毒
B错在忽略了原文给的条件，Honey made from such nectar can cause the effects the texts describe, but 【only if】 eaten fresh，即毒的时效性。核心不在于蜜是否来自这2种植物，在于来自它们的蜜什么时候被吃了。换句话说，种这2种植物 不等同于 产生毒蜜。B选项等于说这2种植物才是毒蜜的原因，是错的。用做实验的方式来说整件事，B选项描述的是一个baseline实验1，无R&O植物，蜂蜜无毒。实验2，加了R / O 或者R&O植物，蜂蜜有时有毒，有时没毒，有一个调节变量时效，毒性是R&O植物和时效共同作用的结果。B选项以偏概全说毒性是R&O单独作用的结果，这是不对滴。登录 或 注册 后可以参加讨论
