1. Since the new publisher took control, a news magazine’s covers have featured only models and movie stars. Previously, the covers had displayed only politicians, soldiers, and business leaders. A leading gossip columnist claimed that the changes made the magazine relevant again. However, many newspaper editorials disagreed and suggested that the new publisher is more interested in boosting sales than in reporting important news events. Which of the following is an assumption necessary for the argument made by the gossip columnist’s opponents?

A The charitable activities of models and movie stars often focus public attention on pressing problems.

B Final authority for choosing the cover subject of the magazine lies with the publisher.

C A magazine can boost sales while highlighting the coverage of important world leaders.

D Some of the movie stars featured are now running for political office.

E Magazine issues with models or movie stars on the covers are purchased at a rate more than three times greater than is the case with issues featuring politicians on the covers.

2. In response to the increasing cost of producing energy through traditional means, such as combustion, many utility companies have begun investing in renewable energy sources, chiefly wind and solar power, hoping someday to rely on them completely and thus lower energy costs. The utility companies claim that although these sources require significant initial capital investment, they will provide stable energy supplies at low cost. As a result, these sources will be less risky for the utilities than nonrenewable sources, such as gas, oil, and coal, whose prices can fluctuate dramatically according to availability. The claim of the utility companies presupposes which of the following?

A The public will embrace the development of wind and solar power.

B No new deposits of gas, oil, and coal will be discovered in the near future.

C Weather patterns are consistent and predictable.

D The necessary technology for conversion to wind and solar power is not more expensive than the technology needed to create energy through combustion.

E Obtaining energy from nonrenewable sources, such as gas, oil and coal, cannot be made less risky.

1.
背景：新出版商掌权后杂志的封面变了
观点：社论们认为新出版商更注重刺激销量而非报道正经新闻
问：哪一个是这个观点的假设？
A.明星的公益活动让公众注意焦点问题（逻辑里面没有提到明星慈善这个事情与此无关)
B.出版商有决定封面的权利（正确? 我们想要得出:因为背景（更改背景）——所以说明结论（出版商只在乎销量不在乎报道内容）这样的因果关系 就要默认出版商能决定封面 如果出版商不能决定封面 那封面变了 这件事本身和出版商无关 不能从中揣测他的想法和态度 所以出版商决定封面这是一个基本假设 因为出版商决定封面 所以在封面变化的时候 我们能看出出版商的态度
C.封面是政治人物杂志会买的好 那按这个逻辑 换完封面以后 销量会下降 变成出版商完全不 care销量了 和现有的结论正好是反着的
D.明星去做政治 他们去不去从政 和封面的变化反映出版商态度无关
E.有具体的数字不对 假设是一个模糊抽象的假设 可以是1可以是2 不能说某一个数字就一定是necessary
2.结论：新能源比传统能源风险小
原因:新能源能够以稳定的低成本输出，而传统能源会因为可获得性而不断大幅波动
我们要找到一个前提条件 让这个因果关系成立
A.公众接受与否和新能源的风险（题目一直说的是造价(成本）风险不是利润风险）无关
B.未来不会有新的传统能源被开发 （有没有这前提都不影响我们的逻辑，有新的被开发此逻辑也成立）
C.天气是一致的且可预测的（如果天气不可预测，那么新能源的输出成本就不再稳定，我们就不能得出原有结论）
D.生产新能源的技术要比传统能源技术便宜（即使贵也不影响远逻辑，新能源还是成本更稳定,还是风险更小）
E.获取传统能源的风险不能降低（没有这个条件逻辑也成立：即使风险可以降低，但这并不影响我说化石能源波动性大风险高，又不是降到零）
