Advertisement: Our competitors’ computer salespeople are paid according to the value of the products they sell, so they have a financial incentive to convince you to buy the most expensive units—whether you need them or not. But here at Comput-o-Mart, our salespeople are paid a salary that is not dependent on the value of their sales, so they won’t try to tell you what to buy. That means when you buy a computer at Comput-o-Mart, you can be sure you’re not paying for computing capabilities you don’t need.
Which of the following would, if true, most weaken the advertisement’s reasoning?
Some less-expensive computers actually have greater computing power than more expensive ones.
Salespeople who have a financial incentive to make sales generally provide more attentive service than do other salespeople.
Extended warranties purchased for less-expensive computers can cost nearly as much as the purchase price of the computer.
Comput-o-Mart is open only limited hours, which makes it more difficult for many shoppers to buy computers there than at other retail stores.
Comput-o-Mart does not sell any computers that support only basic computing.
C：你确定你不会为了不需要的功能付款
削弱：E 因为不卖只有基础功能的电脑，所以客户必须要为不需要的额外的功能付款，而不是因为店员的问题
A为什么错？因为A不直接导致结论。A要导致结论的逻辑链条是：低价格高算力的电脑存在》这个商场有这种电脑》顾客可能买到超出自己需求的算力
但这个逻辑链条的中间环节的信息在素材里在选项里都是缺失的。
所以你买的电脑满足你的需要。
反驳：
X对Y的关系虚弱/ 或者Z 对Y 的影响
那些电脑都不是基础款的电脑。
A 有的比较便宜的电脑反倒有更强大的计算能力。无关
B 有金钱激励机制的销售服务更体贴周到。无关
C 给便宜点的电脑上质保的钱跟电脑话的钱差不多。无关
D C店开门事件短，搞得大家不大容易在他家买到电脑。
E C店不卖只满足基本计算能力的电脑，也就是说C店卖的电脑算力都很强，如果是个普通用户在他家买电脑，就有可能回味多余的性能付钱。
所以E选项是说没有只有计算功能的电脑，是想说有的人只想要有计算功能的电脑但是没有，就肯定会有人买了自己不想要的功能
答案是：不会卖只有基础功能的电脑——》无论如何如果你想买只有基础功能的电脑你都要多花钱——》削弱了结论，中间这个有点难想
b. 看上去无关，除非他说这种attentive service可以帮助你买到需要功能的产品
c.d. 无关
Assuming that you as a customer need only basic computing capacity, then its certain that you have to pay extra money
