这题基本上就是A, D 二选一.
我是觉得system's ability to do sth 的用法有点怪. 不知道这样用法有没有问题.
看了gemj的解释, 似乎especially 的用法更好. 那是不是请你再解释一下像system's ability to do sth的这种用法.
有没有别的例子也是这样呢?

人或动物的就不说啦，非生命的稍来几个：

7.    Snyder et al suggest that caffeine’s ability to bind to A1 and A2 receptors can be at least partially attributed to which of the following?
(A) The chemical relationship between caffeine and phosphodiesterase
(B) The structural relationship between caffeine and adenosine
(C) The structural similarity between caffeine and neurotransmitters
(D) The ability of caffeine to stimulate behavior
(E) The natural occurrence of caffeine and adenosine in the brain

Additional evidence was provided by negative findings: drugs called adrenergic antagonists, which block peripheral adrenaline receptors, disrupted adrenaline’s ability to regulate memory but did not affect memory enhancements produced by glucose that was not stimulated by adrenaline.

20.    The author refers to the results of the experiment using adrenergic antagonists as “negative findings” (line 13) most likely because the adrenergic antagonists
(A) failed to disrupt adrenaline’s effect on memory
(B) did not affect glucose’s ability to enhance memory
(C) did not block adrenaline’s ability to increase blood glucose levels
(D) only partially affected adrenaline’s ability to enhance memory
(E) disrupted both adrenaline’s and glucose’s effect on memory

语法一个比较简单的解法还是认为ABILITY TO 比CAPABILITY OF优先。这样就只能选A了

语法：
Sulfur dioxide, a major contributor to acid rain, is an especially serious pollutant because it diminishes the respiratory system’s ability to deal with all other pollutants.

A. an especially serious pollutant because it diminishes the respiratory system’s
ability to deal

B. an especially serious pollutant because of diminishing the respiratory system’s
capability of dealing

C. an especially serious pollutant because it diminishes the capability of the
respiratory system in dealing

D. a specially serious pollutant because it diminishes the capability of the respiratory
system to deal

E. a specially serious pollutant because of diminishing the respiratory system’s
ability to deal

--------------------------------------

especially adv
1 more than other things or people, or much more than usual
He's always making comments about her appearance, especially her weight.
She's especially interested in American
poetry.
2 for one particular person, purpose, or reason
I cooked this meal especially for you.

specially adv
for a particular purpose
They searched the building with specially trained dogs.
I made this specially for you

From defibations of both words, we can conclude that the second meaning of especialy iis the same as that of specially, that is for a particular purpose.

But this item isapparently designed to  compare Sulfur dioxide with other things, therefore, we should use especially here.
I agree with a.

  逻辑：

Kernland imposes a high tariff on the export of unprocessed cashew nuts in order to
ensure that the nuts are sold to domestic processing plants. If the tariff were lifted and unprocessed cashews were sold at world market prices, more farmers could profit by growing cashews. However, since all the processing plants are in urban areas, removing the tariff would seriously hamper the government’s effort to reduce urban unemployment over the next five years.

Which of the following, if true, most seriously weakens the argument?

A. Some of the by-products of processing cashews are used for manufacturing paints
and plastics.

B. Other countries in which cashews are processed subsidize their processing plants.

C. More people in Kernland are engaged in farming cashews than in processing them.

D. Buying unprocessed cashews at lower than world market prices enables cashew
processors in Kernland to sell processed nuts at competitive prices.

E. A lack of profitable crops is driving an increasing number of small farmers in
Kernland off their land and into the cities.

-----------------------------------

e is correct answer.

  Business Consultant: Some corporations shun the use of executive titles because they
fear that the use of titles indicating position in the corporation tends to inhibit communication up and down the corporate hierarchy. Since an executive who uses a
title is treated with more respect by outsiders, however, use of a title can facilitate an executive’s dealings with external businesses. The obvious compromise is for these 24 executives to use their corporate titles externally but not internally, since even if it is widely known that the corporation’s executives use executive titles outside their organization, this knowledge does not by itself inhibit communication within the corporation.

In the consultant’s reasoning, the two portions in boldface play which of the following roles?

A. The first presents an obstacle to achieving a certain goal; the second presents a
reason for considering that goal to be undesirable.

B. The first is a consideration that has led to the adoption of a certain strategy; the
second presents a reason against adopting that strategy.

C. The first describes a concern that the consultant dismisses as insignificant; the
second is a consideration that serves as the basis for that dismissal.

D. The first is a belief for which the consultant offers support; the second is part of
that support.

E. The first is a belief against which evidence is offered; the second is part of the
evidence offered against that belief.

i agree with e.

about "consideration"
please refer to the following linnk:

我覺得是C﹐D﹐B
1 大家都認為A對嗎﹖不可以說capability in doing嗎﹖sth's ability總是有些奇怪。誰有capability的用法呢﹖
2 E我認為是支持的﹐不是weaken的﹐所以是錯的﹐如果降低tariff,農民進城了﹐失業更多啦。所以和government的concern是支持關係
3 其他的﹐除了b,似乎都沒有道理。
