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.

Unfortunately, the tulu is easily devastated by a contagious fungal rot.

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


【申友解析】


正确答案：D


题干：TULU是一种流行的景观植物，它们并不能自然繁殖，只能通过专业的园艺公司来培植和售卖。不幸的是，TULU很容易被传染性的真菌所摧毁。政府计划通过要求所有TULU在被贩卖前进行真菌测试来保障园艺师的利益。可是，寿命30周之内被感染的TULU是不能被有效检测到真菌感染的，同时，大部分TULU在24周之内就已经被售出了。
题目：下面哪一项措施，如果被政府采用，可以克服目前面临的对TULU真菌感染检测上的问题。
分析：PLAN类型题目，目的是检测出TULU的真菌感染，那么我们主要的注意力要放在TULU被真菌感染和有效检测方法的时序关系上。
选项A, 官方声明TULU在30周之内无法有效检测真菌感染。不解决任何问题，排除！
选项B，要求30周之内的TULU贴标签说明，同样不解决有效检测问题，排除！
选项C，研究可能的办法来检测24周之内的TULU的真菌感染，开始研究本身不解决问题，只有研究得出积极成果之后才能解决问题，亦即主观意愿不解决客观问题！
选项D，保证TULU在30周之内不被卖出，从根本上可以解决有效检测问题，30周之后的TULU是可以被有效检测出是否被真菌感染的，正确！
选项E，隔离策略同样不能解决TULU有效检测的时间限制问题！错误！
