题目：

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?

选项:

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 on 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.

这道题正确答案是B，我选对了，但是思路不知道对不对，麻烦老师点评一下，谢谢！原文读出来：mining和refining nickel是很贵的，研究人员发明了一种可替代的方法去extracting N通过SP，一个植物从soil里面吸收和储存N。研究人员怎样（我猜是种植）一个S植物在N丰富的soil里面。通过化学地怎样N，这个植物生产了100p的N在一个总的成本轻微高于现在用m。问题问的是：支持用新的方法能够经济 A 天气能够最大化S的生长率，无关 B 一个目标（S生长和被卖是持续的）比它的成本多，和经济有点沾边，留着 C 用新技术和传统技术之间的空气污染之比，无关 D 两种用S的土地之比，无关 E soil的含量，无关因此选B

提问：

有些逻辑题的问题很长内容丰富，问的可能也会是原文几个主要意思中的一个，做这类题时是不是就不能光去看选项和原文哪个更相关，而是去看选项和问题哪个更相关呢？那会不会产生和原文没提及或者需要推断得出的选项？
