这三大类型分别是argument construction、argument evaluation和formulating and evaluating a plan of action，我们可以称之为论点构建题、论点评价题和评价行动方案题三种。下面是详细内容。
一、GMAT逻辑论点构建题的定义
论点构建原名argument construction，是Bible中提到的第一类题型。这类问题主要让考生识别论述的基本结构、正确得到的结论、隐含的假设、有力的解释性假说以及结构上相似的论点的类似性。换句话说，这类题型考察的就是我们识别怎样的前提或附加信息可以得出、支持或削弱既定结论的能力。从根本上看，就是在考察演绎推理的能力。

二、GMAT逻辑论点构建题的考察内容
这一类的问题主要要求识别或找到：
1、论述的基本结构(the basic structure of an argument)。
2、正确得到的结论(properly drawn conclusion)。
3、所基于的假设(underlying assumption)。
4、被强有力支持的解释性假说(well-supported explanatory hypotheses)。
5、结构上相似的论点的平行结构(parallels between structurally similar arguments)。

三、GMAT逻辑论点构建题的例题分析
为了帮助大家理解论点构建题，小编整理了一道例题，通过分析例题来体会这类题型的考察方式和答题方法。
1、例题。
Installing scrubbers in smokestacks and switching to cleaner-burning fuel are the two methods available to Northern Power for reducing harmful emissions from its plants. Scrubbers will reduce harmful emissions more than cleaner-burning fuels will.(前提：S比C更有效) Therefore, by installing scrubbers, Northern Power will be doing the most that can be done to reduce harmful emissions from its plants.(结论：装S 已经做到最好了)Situation A power plant can reduce emissions by installing scrubbers and also by switching to cleaner-burning fuel; installing scrubbers reduces emissions more than switching fuels. By installing scrubbers, the company is doing the most that it can do.
Which of the following is an assumption (Defende：排除可以更好可能性)on which the argument depends?
(A) Switching to cleaner-burning fuel will not be more expensive (没讨论)than installing scrubbers.
(B) Northern Power can choose from among various kinds of scrubbers, some of which are more effective than others.
(C) Northern Power is not necessarily committed to reducing harmful emissions from its plants.
(D) Harmful emissions from Northern Power’s plants cannot be reduced more by using both methods together than by the installation of scrubbers alone.(Defender;取非：还有更好方法;削弱：已经做到最好。
(E) Aside from harmful emissions from the smokestacks of its plants, the activities of Northern Power do not cause significant air pollution.
2、正确答案：
D Correct. If harmful emissions could be reduced even more by using both methods, then installing scrubbers alone will not be the most that the company can do to reduce harmful emissions.
3、例题分析：
Reasoning What assumption does the argument depend on? The assumption will be a statement that has to be true in order for the argument’s premises to provide a solid reason for believing its conclusion. Here, the conclusion that the company is doing the most that it can do is based on believing that choosing one or the other of the two options will be more effective than choosing both options together. This argument assumes, then, that installing the scrubbers alone is just as effective as both installing scrubbers and switching to cleaner-burning fuel.
A The relative costs of the two options indicate nothing about whether by installing scrubbers the company will have done the most that it can to reduce harmful emissions.
B Even if the company installs the most efficient scrubbers, it may be that there is more that Northern Power could do to reduce harmful emissions.
C Even if the company is fully committed to reducing harmful emissions, it could be that installing scrubbers is the most it can do to reduce harmful emissions.
E Even if this were not assumed and the company’s other activities did cause significant air pollution, it could still be that installing scrubbers is the most that the company can do to reduce harmful emissions from its plants; perhaps any of its other activities that do cause significant air pollution have nothing to do with its plants—for example, pollution coming from trucks the company uses.
