下面百利天下小编为大家整理了一种非演绎题型——解释题型，故名思议，这种题型意在解释提干中叙述的不合理之处，使现象和结果(前提与结论)之间的联系更加顺理成章。
一、GMAT逻辑explain题型分析
1、explain题的定义。
explain题型，又称解释题。通常需要对题目的某一个部分做出合理解释。这种题目的提干通常叙述某一现象，然后从这一现象中得出一个貌似相反的结果。要求我们选出一个条件(正确答案)，来解释这种看似矛盾的事件，使前提和结论之间的推倒过程更加顺利成章。
2、explain题型题的标志：
1)标志词：标志性词语：explain、reason、account for…这些标志词一旦出现在某道题目的问题中，我们基本上可以判定这道题目为解释题。
2)典型问法。
Which of the following, if true, would help resolve the apparent paradox presented above?
Which of the following statements, if true, would best explain the 1984 decrease in productivity?
Which of the following, if true, best explains the sharp rise in the average price of new houses?

二、GMAT逻辑explain题如何解题
1、explain题的解题思路。
解释题的解题思路通常是先寻找可以合理解释文中现象的选项，通常为解释矛盾现象原因，或计划不成功的原因，类似于削弱题。
2、explain题的解题技巧。
1)假设题一般解法是先分析结构，找出A, however B,将however看作therefore，解释时思考整体。
2)如果解释的对象是两者比较，那么正确选项必须体现此相对量。
3)如果解释的对象再说上升下降，那么正确选项必须体现变化。

为了帮助大家更好地了解解释题型的解题方法如何运用，前程百利小编为大家整理了下面两道例题。
例题：OG13-P500-3
Suncorp, a new corporation with limited funds, has been clearing large sections of the tropical Amazon forest for cattle ranching. This practice continues even though greater profits can be made from rubber tapping, which does not destroy the forest, than from cattle ranching, which does destroy the forest.
Which of the following, if true, most helps to explain why Suncorp has been pursuing the less profitable of the two economic activities mentioned above?
(A) The soil of the Amazon forest is very rich in nutrients that are important in the development of grazing lands.
(B) Cattle-ranching operations that are located in tropical climates are more profitable than cattle-ranching operations that are located in cold-weather climates.
(C) In certain districts, profits made from cattle ranching are more heavily taxed than profits made from any other industry.
(D) Some of the cattle that are raised on land cleared in the Amazon are killed by wildcats.
(E) The amount of money required to begin a rubber-tapping operation is twice as high as the amount needed to begin a cattle ranch.

题目：解释为何S公司选择低利润的畜牧业而非高利润且环保的橡胶生产业。
A选项，引入无关对象讨论无关属性。
B选项，无关属性比较。
C选项，逻辑方向错误。
D选项，引入无关对象讨论无关属性且逻辑方向错误。
E选项正确。
例题：OG13-P5010-6
Parland's alligator population has been declining in recent years, primarily because of hunting. Alligators prey heavily on a species of freshwater fish that is highly valued as food by Parlanders, who had hoped that the decline in the alligator population would lead to an increase in the numbers of these fish available for human consumption. Yet the population of this fish species has also declined, even though the annual number caught for human consumption has not increased.
Which of the following, if true, most helps to explain the decline in the population of the fish species?
(A) The decline in the alligator population has meant that fishers can work in some parts of lakes and rivers that were formerly too dangerous.
(B) Over the last few years, Parland's commercial fishing enterprises have increased the number of fishing boats they use.
(C) The main predator of these fish is another species of fish on which alligators also prey.
(D) Many Parlanders who hunt alligators do so because of the high market price of alligator skins, not because of the threat alligators pose to the fish population.
(E) In several neighboring countries through which Parland's rivers also flow, alligators are at risk of extinction as a result of extensive hunting.
例题解析：
题目：P地鳄鱼数量最近几年一直在下降，主要由于对鳄鱼的猎杀。而鳄鱼喜欢捕食的淡水鱼是P地居民所喜爱的食物，那么P地居民就希望鳄鱼数量的减少能带来淡水鱼数量上升这个结果。但是淡水鱼数量也减少了，还是在当地居民没有增加淡水鱼消费量的情况下。
题干：解释鱼群数量下降这个现象。
A选项说鳄鱼数量下降会使得渔民可以在之前危险的地方进行作业，题目中已经排除了人为因素对鱼群数量的影响，不能忽视或者否定原文给定的信息。
B选项说P地的渔业企业增加了捕鱼船的数量，跟A选项问题一样。
C选项说鳄鱼不仅仅吃淡水鱼，同时也吃另一种喜欢捕食淡水鱼的物种，那么鳄鱼数量减少，这里所说的另一种喜欢捕食淡水鱼的物种数量会上升，能够导致淡水鱼数量下降这个结果。正确!
D选项讨论为什么要捕杀鳄鱼，与题目论点无关。
E选项说邻国鳄鱼濒临灭绝，无关选项。
