The tulu, a popular ornamental plant, does not reproduce naturally, and is only bred and sold by specialized horticultural companies. Unfortunately, the tulu is easily devastated by a contagious fungal rot. The government ministry plans to reassure worried gardeners by requiring all tulu plants to be tested for fungal rot before being sold. However, infected plants less than 30 weeks old have generally not built up enough fungal rot in their systems to be detected reliably. And many tulu plants are sold before they are 24 weeks old.
Which of the following, if performed by the ministry, could logically be expected to overcome the problem with their plan to test for the fungal rot?

Which of the following, if performed by the government ministry, could logically be expected to overcome the problem with their plan to test for the fungal rot?
(A) Releasing a general announcement that tulu plants less than 30 weeks old cannot be effectively tested for fungal rot
(B) Requiring all tulu plants less than 30 weeks old to be labeled as such
(C) Researching possible ways to test tulu plants less than 24 weeks old for fungal rot
(D) Ensuring that tulu plants not be sold before they are 30 weeks old
(E) Quarantining all tulu plants from horticultural companies at which any case of fungal rot has been detected until those tulu plants can be tested for fungal rot
至于说选项不能攻击前提,首先要知道前提是什么:And many tulu plants are sold before they are 24 weeks old. 发生在现在。
选项D是指政府要保证tulu plants not be sold before they are 30 weeks old. 这是指对未来的规划,没有攻击前提:当前tuluplants are sold before they are 24 weeks old,反而是基于这个前提,才要政府去改变未来这个现状。
攻击前提的做法应该是这样:直接否定说Government finds out that many tulu plants are not sold before they are 24 weeks old。
