It is crucially important to farmers that the herbicides they use to control weeds not damage their crops. One very effective herbicide is safe for corn, but soybeans are damaged even by the herbicide's residue, which remains in the soil more than a year after the herbicide is applied. Soybeans and corn are not sown together in the same field; nevertheless, most farmers are reluctant to use the herbicide on their corn.

Which of the following, if true, provides the strongest justification for the farmers' reluctance?

正确答案: B

[分享]916二战又败...

考前就决定,不管这次结果如何,要上来CD回馈。刚考完,伤痕累累,很多东西都忘光了,只能回忆一些。希望大家别介意!

AA:The following appeared in a mermorandum from the owner of Carlo's Clothing to the staff.

“Since Disc Depot, the music store on the next block, began a new radio advertising campaign last year, its business has grown dramatically, as evidenced by the large increase in foot traffic into the store. While the Disc Depot’s owners have apparently become wealthy enough to retire, profits at Carlo’s Clothing have remained stagnant for the past three years. In order to boost our sales and profits, we should therefore switch from newspaper advertising to frequent radio advertisements like those for Disc Depot."

AI:Employers benefit more from the energy and new idea of younger works than the experience and wisdom of older workers.

Math:重复一样的就不多提,提变型or新型。

1. 给出三角形PQR,PR. PQ. QR. 分别是8.4.x. 问x对应的那个角是不是大於90度?

    1) x>4.5   

    2) x<6.5 

我遇到变体:题目一样是三角形PQR,三个边对应长度一样是8.4.x.,但注意:对应出来的边和原来寂静不同,8会是斜边, 4和x变成两股,题目还给了4<X<8 ,问斜边8对应的角度是否大於90度。(大家叁考看)

2. 遇到一到韦恩图题目,详细题目我忘了,建议大家多复习韦恩图的相关问题。

3. 五个数 110. 130. 170. 200. X,问下列哪一项有可能会是这五个数的中位数?

(I) 130 

(II) 150

(III)180

<详细数字不确定是不是没记错>

这题我选(I) and (II) 

剩下的数学都是比较琐碎的记忆,就不分享。

Verbal:我的罩门,So只提一道逻辑,大家叁考看看,因为细节不是记得很清楚。

说有一种除草剂(or农药)对Corns没有影响,但对soybeans会有不好的影响,然後某人(忘了是政府还是农民)就说,因为他们是采轮耕,(我想应该是指轮流种Corns和Soybeans吧...),所以他们只在全部种Corns的时候用这种农药,这麽一来,就不会影响到Soybeans。问weaken。

我选"这种农药会残留在这块土里一年多",如果我的理解没有错的话,虽然农民只在全部种Corns时使用农药,但农药会残留在土里,因此当轮流种到Soybeans时,Soybeans仍会受到影响。That's why I choose this. 大家考到时,可以再看看其他选项。

ls说得没错,lz加油。另外,那道种玉米的CR应该是这道GWD的变体吧?如果是的话,你的答案应该是正确的,因为这道题只是把答案和选项换了一下位置。

17. GWD31-Q17

It is crucially important to farmers that the herbicides they use to control weeds not damage their crops. One very effective herbicide is safe for corn, but soybeans are damaged even by the herbicide’s residue, which remains in the soil more than a year after the herbicide is applied. Soybeans and corn are not sown together in the same filed; nevertheless, most farmers are reluctant to use the herbicide on their corn.

Which of the following, if true, provides the strongest justification for the farmers’ reluctance?

 

A.      The residue of the herbicide in the soil a year after application is not enough to control most weeds effectively.

B.       To maintain the nutrients in the soil, corn and soybeans are often planted in a field in alternate years.

C.      The demand for soybeans is growing faster than is the demand for corn.

D.      For maximum yield, soybean plants are grown closer together to each other than are corn plants.

E.       The application of herbicides is less critical for soybean than for corn crops.

key:B
