这三大类型几乎涵盖了逻辑的所有题目，它们和逻辑十几种题型的划分是不同的定义维度，所以两者是交叉的关系。大家可以从不同的角度来解题。
一、GMAT逻辑论点评价题的定义
论点建设题主要是让考生识别正确得到的结论，论述的基本结构，隐含的假设，有效的解释性假说以及论点结构的相似性。简单来说，就是识别有效信息，得出既定结论的能力，从本质上说主要考察考生的推理演义能力。

二、GMAT逻辑论点评价题的考察内容
这一方面的问题主要要求在分析既定论点的基础上识别：
1、加强或削弱既定论点的因素(factors that would strengthen or weaken the given argument)
2、在进行论述时所犯的推理错误(reasoning errors committed in making that argument)
3、进行论述时所使用的方法(the method by which the argument proceeds)

三、GMAT逻辑论点评价题的例题分析
为了帮助大家理解论点评价题，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。
例题。
Outsourcing is the practice of obtaining from an independent supplier a product or service that a company has previously provided for itself. Since a company’s chief objective is to realize the highest possible year-end profits,(前提/目标) any product or service that can be obtained from an independent supplier for less than it would cost the company to provide the product or service on its own should be outsourced.(假设结论/措施，削弱结论—>结论不成立;措施的缺陷—>目标达不到)
Which of the following, if true, most seriously weakens the argument?
(A) If a company decides to use independent suppliers for a product, it can generally exploit the vigorous competition arising among several firms that are interested in supplying that product.
(B) Successful outsourcing requires a company to provide its suppliers with information about its products and plans that can fall into the hands of its competitors and give them a business advantage.
(C) Certain tasks, such as processing a company’s payroll, are commonly outsourced, whereas others, such as handling the company’s core business, are not.
(D) For a company to provide a product or service for itself as efficiently as an independent supplier can provide it, the managers involved need to be as expert in the area of that product or service as the people in charge of that product or service at an independent supplier are.
(E) When a company decides to use an independent supplier for a product or service, the independent supplier sometimes hires members of the company’s staff who formerly made the product or provided the service that the independent supplier now supplies.
1、正确答案：B is Correct.
This statement properly identifies one disadvantage of outsourcing: the company no longer controls access to its information and plans. (Incomplete information. The author fails to consider all of the possibilities,没有考虑所有可能性 or relies upon evidence that is incomplete. 证据不完整
This flaw can be attacked by bringing up new possibilities or information.提出新可能性/新信息)With the increased possibility of competitors’ gaining access to its proprietary information, the company’s business is put at risk.
2、例题分析：
Situation In order to realize the highest year-end profits, a company should outsource any service or product that can be obtained from an independent supplier for less than it would cost the company to provide that service or product itself.
Reasoning What weakens this argument? When could outsourcing a service or product result in a business disadvantage or lower profits?(削弱目标) It is clear that the company must give independent suppliers enough information to enable them to provide the contracted products and services, but this means that the company can lose control over who has possession of such critical information. If the information becomes known to the company’s competitors and gives them a business advantage, the company’s profitability may be harmed rather than helped by outsourcing. (信息会被泄漏给竞争对手)This possibility weakens the argument.
3、选项分析：
A This would strengthen the argument since the pricing competition among independent suppliers is an advantage for the company. exploit the vigorous competition利用激烈的竞争
C Providing examples of the tasks typically outsourced or handled internally does not affect the argument.
D Expertise in a particular area is an advantage of outsourcing and thus a strength of the argument.
E The supplier’s hiring of members of the company’s staff to handle work no longer performed within the company is not shown to be a disadvantage.
