29. 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 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

解惑了，谢谢~是不是还有一层原因在于，possible并不肯定，万一没有研究出来还是没有解决问题？

在本题给出的前提下解决问题，最有效的就是确保30 weeks后卖出。

个人觉得，题目问的是logically be expected，而C答案是

technically或者hypothetically 能够成立，而且道高一尺魔高一丈，即

以唯一可行的方法就是规定出售时间的下限，而不是去迎合这个无极限的
