CR570-582题

【OG18-P516-573题】

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

(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

答案：

��明实现plan过程中存在的两个问题：30周内fungal rot达不到足够的检测量（达到30周才能准确检测出fungal rot）+很多公司24周内就把tulu卖了。这两点明显存在矛盾。题干核心：如何才能实现plan，plan具体指的是require all tulu plants to be tested for fungal rot before being sold。注意all to be tested是关键！分析选项： 30周检测是硬性条件，只能从另一矛盾入手，D使得矛盾顺利解决。 A.announcement和test是两回事 B.label和test也是两回事 C.存在两方面问题1真能有这样的技术么？2商家为躲避检测可以继续缩短卖的时间选项显得政府太被动 D.“对发现fungal rot个例的公司的所有tulu进行隔离，直到可以检测（30周）为止”换句话说，公司会觉得如果不抓紧卖，说不定哪天点背就被查到了那时候想卖都卖不了了。那必然会有更多公司24周内就开始卖tulu。
