8. (B)选项有一个only，就要提高警觉，只有单纯看秀不吃饭的人。跟本文中讨论live
show & restaurants就不合啦，因为餐厅要吃饭。

49这题我的想法是对于逻辑强的消费者，喜欢用数字评估东西，来判断有没有一分钱一分货，而user-friendliness看不到、摸不到，很难评估，所以会对他们而言是一种困扰，他们喜欢看到数据化的陈述。

        讨论oil
gas与natural gas的价格，议题焦点在$，因此E讲distribution，可视为无关选项。

至于B答案呢，很合理解释同样的东西，消费者选便宜的。

Oil gas ↓----> (therefore暗示因果关系) natural gas↓

请指教

注意题中的premature and irrelevant.  irrelevant, 无关. A考虑原来的电脑的friendliness不就relevant了吗?

如果现有的计算机型号在user-friendly是不错的，为何这群人会觉得oddly premature and irrelevant?这是我当初看的时候觉得很奇怪的地方。因为句中写potential buyers就表示他有想要买的意愿，不是已经满足了的人。加上whether这个字是「是否」，后面句意是：其重视….不管是否够不够user-friendly。

或许有其它人可以给意见，可能还有更好可以跟你解释的说法。
