Many gardeners believe that the variety of clematis vine that is most popular among gardeners in North America is jackmanii. This belief is apparently correct since, of the one million clematis plants sold per year by the largest clematis nursery in North America, ten percent are jackmanii.
Which of the following is an assumption on which the argument depends?
The nursery sells more than ten different varieties of clematis.
The largest clematis nursery in North America sells nothing but clematis plants.
Some of the 【GL:i】jackmanii【/GL:i】 sold by the nursery are sold to gardeners outside North America.
Most North American gardeners grow clematis in their gardens.
For all nurseries in North America that specialize in clematis, at least ten percent of the clematis plants they sell are 【GL:i】jackmanii【/GL:i】.
如果10%就是最大销量的话，至少得有十种以上的种类
我觉得可以从反面来推导，假如销售的种类小于10种，比如说有9种，而10%又是最大的销量的话，那么剩下的8种所占的比例是90%，平均下来都大于10%，自然是不成立的。
才10%就是销量最好的，说明必须有超过10种商品。才可能让10%成为最多的占比
BCD都无关
E 至少有10%的植物是jack 。。。可能有其他的比这个多
和骨折 透片 那题相似
枚举推理 CQ2 其他样本问题
重点在于more than ten。因为小于等于10 的话，就绝对不成立了
那如果是11个样本，我可以其中9个占了8%，剩下两个各占6%和10%，那jackmaniu也是10%，不就不是唯一一个sales最好的了吗
