Because mining and refining nickel is costly, researchers have developed an alternative method for extracting nickel using Streptanthus polygaloides, a plant that absorbs and stores nickel form the soil as it grows. The researchers incinerated a crop of Streptanthus they grew in nickel-rich soil. By chemically extracting nickel from the ash, they produced 100 pounds of nickel per acre of land at a total cost per pound slightly above that of current mining.

Which of the following, if true, most strongly supports the conclusion that the use of Streptanthus to extract nickel will be commercially adopted?

正确答案: B

新记起的verbal 鸡精,V42

 我补充下JJ,应该大都是新出现的

AI: nations should cooperate to develop regulations to limit children's access to adult material on the internet.

SC: Many a man among those who had heard the horror news was very pleasantly glad that the plans returned on time....差不多这个意思,黑体部分是考点,确定上述是正确的。

SC2: devote to doing and doing, 注意不是to do and do,

CR: 有一个爆长的,相当于小阅读了: 大致说矿物提炼,现在的方法成本很大,有一种新的方法被发明出来了,利用藻类从土壤里吸取元素,这样成本会低一些。但是因为*&&*, 所以不能采用。问加强。记不清楚了。

CR   也比较长,现在油价升高了,所以制造厂的成本随着上升,他们的生存处境变得很艰难。后来说为了应对压力,现在这些manufacturers 发现了一种替代的方法,就是从饭店或者小餐馆收集那些废弃的食物油提炼利用,这样成本会降低15%,并且政府会有一个什么什么税收来cover使用这种替代方法的设备投资费用,所以这种方法采用的话会减缓生存压力。问削弱。  选项有这些饭店也会自己重复利用这些废弃油(这个有干扰,当时觉得这个像答案),还有政府的税收补贴不会cover所有设备投资费用等,后面有个答案,好像是E,说随着这种替代方法的采用,这种废弃食用油的价格也有升高。(这个我确定是正确答案,因为这样使得采用这种油的价格优势失去了)。

有几道JJ里的CR,不过都出现在20题之后。

阅读三个是JJ, 另外有一个是公司治理的,大概是公司的财务压力和破产之类的,文章不短,但是有经济类背景的话太好懂了。

Quant相信已经很翔实了,就不补充了。

这个矿物提炼的CR,加强是寂静里那个藻类不会占用corn等生长的土壤么?

多谢楼主jj,帮忙看看那个土壤提取矿物质的是不是这道题:

T-3-Q37.
                

Because mining and refining nickels is costly, researchers have developed an alternative method for extracting nickels using Streptanthus polygaloides, a plant that absorbs and stores nickel from the soil as it grows. The researchers incinerated a crop of Streptanthus they grow in nickel-rich soil. By chemically extracting nickel form the ash, they produced 100 pounds of nickel per acre of land at a total cost per pound slightly above that of current mining.

Which of the following, if true, most strongly supports the conclusion that the use of Streptanthus to extract nickel will be commercially adopted?

A.      The season in which the researchers grew Streptanthus was an unusually favorable one, with the right amount of precipitation to maximize the growth rate of Streptanthus.

B.       Because lowering the concentration of nickel in the soil can make land much better for agriculture in general, a plot in which Streptanthus has been grown and harvested can be sold for substantially more than it cost

C.      More air pollution is generated for each pound of nickel produced by extracting it from Streptanthus than is generated using conventional mining and refining

D.      The land on which the researchers planted Streptanthus was unusually free of the various weeds that can compete with Streptanthus for water, nutrients, and sunlight.

E.       It is extremely rare for soil to contain higher concentrations of nickel than the concentrations present in the researchers’ experimental plot.

答案B
