两道逻辑题的分析检测 - ChaseDream

下列两道题我写了思路，大家帮忙看看有什么问题并解决一下

In the past, most children who went sledding in the winter snow in Verland used wooden sleds with runners and steering bars. Ten years ago, smooth plastic sleds became popular; they go faster than wooden sleds but are harder to steer and slow. The concern that plastic sleds are more dangerous is clearly borne out by the fact that the number of children injured while sledding was much higher last winter than it was ten years ago.

Which of the following, if true in Verland, most seriously undermines the force of the evidence cited?

A. A few children still use traditional wooden sleds.不沾，多少小孩使用wooden sleds.

B. Very few children wear any kind of protective gear, such as helmets, while sledding.不沾，多少小孩穿防身服

C. Plastic sleds can be used in a much wider variety of snow conditions than wooden sleds can.沾边，适用于更多的情况下

D. Most sledding injuries occur when a sled collides with a tree, a rock, or, another sled.伤是在什么情况下发生的，不沾

E. Because the traditional wooden sled can carry more than one rider, an accident involving a wooden sled can result in several children being injured.
为什么导致孩子受伤。

我的思路是：A,B,C都跟受伤没有关系，就首先排除了；然后在D,E中找出一个更明确，更与问题一致的选项。可是答案选C，怎么解释？？？

A manufacturer of workstations for computer-aided design seeks to increase sales to its most important corporate customers. Its strategy is to publish very low list prices for workstations in order to generate interest among the buyers for those corporations.

Which of the following, if characteristic of the marketplace, would tend to cause the manufacturer’s strategy to fail?

A. The proposed list prices would seem low to a typical buyer for the manufacturer’s most important corporate customers.沾边，价格低

B. The capabilities of workstations suitable for given jobs are not significantly different among various manufacturers.不沾，能力相不相同

C. The manufacturer’s most important corporate customers employ as buyers persons who are very knowledgeable about prices for workstations for customer-aided design.不沾，客户些是什么样的人

D. Customers differ significantly in the percentage of resources they can devote to computer workstations.不沾，但说不清楚为什么

E. Buyers for corporations that purchase workstations for computer-aided design receive bonuses for negotiating large discounts from the list price.购买方能不能得到红利

我觉得E给对方红利，是会损失，但是A直接说了降价，不是更好吗？为什么A不对呢？

第一题。C选项强调plastic用途更广泛的意思是在暗示“用途广，受伤的几率大”，所以受伤人数的上升不能说明P更危险，很有可能是滑雪环境本身就很危险，而如果在这样的环境下，不使用P,可能会有更多的人受伤！

第二题，价格对那些VIP来说比较低，我觉得在A选项成立的情况下，strategy会成功的！

第二题解释的很好，第一题我还是有点疑问，D不就是说的在别的情况下导致的受伤吗？为什么他不对？谢谢
