United Lumber will use trees from its forests for two products.  The tree trunks will be used for lumber and the branches converted into wood chips to make fiberboard.  The cost of this conversion would be the same whether done at the logging site, where the trees are debranched, or at United's factory.  However, wood chips occupy less than half the volume of the branches from which they are made.

The information given, if accurate, most strongly supports which of the following? D

(A) Converting the branches into wood chips at the logging site would require transporting a fully assembled wood-chipping machine to and from the site.

(B) It would be more economical to debranch the trees at the factory where the fiberboard is manufactured.

(C) The debranching of trees and the conversion of the branches into chips are the only stages in the processing of branches that it would be in United's economic advantage to perform at the logging site.

(D) Transportation costs from the logging site to the factory that are determined by volume of cargo would be lower if the conversion into chips is done at the logging site rather than at the factory.

(E) In the wood-processing industry, branches are used only for the production of wood chips for fiberboard.

还有一道，麻烦大家了：

Situation:  For five years the Souper restaurant chain has maintained rapid sales growth in Danport, primarily by opening new restaurants that draw patrons away from other restaurants in their vicinity.

Goal:  Souper wishes to achieve continued rapid sales growth in Danport over the next two years.

Proposal for consideration:  Continue to open new restaurants in Danport during the next two years at the same rate as in the last two years.

In light of the situation, which of the following, if true, most strongly argues that adopting the proposal would be an ineffective way of achieving the goal? D

(A) At times at which customers find Souper restaurants too crowded, they often go to other restaurants nearby.

(B) The Souper chain has generally opened new restaurants in locations that are in the vicinity of a large number of other restaurants.

(C) Souper restaurants generally offer a much smaller variety of foods than many of the other restaurants in their vicinity.

(D) Virtually all potential sites for new Souper restaurants in Danport are located in the vicinity of existing Souper restaurants.

(E) Souper restaurants have always offered meals that are somewhat less expensive than meals at restaurants that compete with Souper for patrons.

这道题我想选E

第一题

题目说 无论是在工厂加工，还是在砍树的地方就地加工，加工费是一样的。

但是木头被切成WOOD CHIPS以后，占的体积比直接的一根木头要小很多

D答案说，如果把货物从伐木场运到工厂的费用是由货物的体积决定，那么先将木头切了再运到工厂会比直接运到工厂直接加工便宜。因为木头切了体积小嘛～～

我估计你是没有遵从推断题逻辑的“白痴原则”，你想太多。也许你在想“为什么木头都切了还要运到工厂”吧。题目没说的，一律不管

第二个  削弱题。先看结论。结论说要和以前一样的速度开新店。要削弱，就是说和以前一样的速度开新店不会有更多的好处了。D答案说 如果继续开新店，可能的新店店址都在已经有分店的地区了，这样开新店就是自己抢自己的客人，那么就不会有SALE的增长了。 E答案说的是 这个店为什么能够用开新店抢到其他店的客人，而没说继续开新店会不会和以前能够增长SALE。

削弱题一定要看好结论。
