GMAT逻辑题一直以来是不少考生的弱项，因为逻辑题考查的不只是考生对于英文题目的阅读和理解能力。考生必须具备一定的逻辑推理思维能力才能做好此类题目。下面小编就通过一些GMAT逻辑真题的完整分析来为大家讲解这一难点题型的解题思路和技巧。
例题分享：
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

题目翻译：
T是一种非常流行的观赏性植物，它不能够自行繁殖，只能通过专业的园艺公司实现育种与出售。不幸的是，T很容易被一种致命的真菌破坏。为了安抚园艺师们，政府要求所有的T在出售之前进行真菌的检验。但是，年龄在30周以下的T因为真菌量太少而往往无法被检测出来，而很多T在其生长至24周之前就已经被售出了。以下哪一项可以帮助政府解决这一问题。
解题思路：
找到一个可以保证检验有效的方法。
逐项分析：
A、通告称年龄在30周以下的T无法有效检测真菌。这只会让园艺师更加恐慌，起不到任何解决问题的作用。
B、给所有年龄在30周以下的T贴上标签。无法解决问题。
C、找到可以有效检测年龄在24周以下的T的办法。此项为弱支持项，在没有其他更好的选项时可选此项。
D、正确选项。因为30周以下的T无法有效检测真菌，但30周以上的T可以。只需要保证所有的T都在30周以上卖出，政府的计划就是行之有效的。
E、无关项。
正确选项：
D
