Although the school would receive financial benefits if it had soft drink vending machines in the cafeteria, we should not allow them. Allowing soft drink machines there would not be in our students' interest. If our students start drinking more soft drinks, they will be less healthy.
The argument depends on which of the following?
If the soft drink vending machines were placed in the cafeteria, students would consume more soft drinks as a result.
The amount of soft drinks that most students at the school currently drink is not detrimental to their health.
Students are apt to be healthier if they do not drink soft drinks at all than if they just drink small amounts occasionally.
Students will not simply bring soft drinks from home if the soft drink vending machines are not placed in the cafeteria.
The school's primary concern should be to promote good health among its students.
情景:虽然放一个饮料自动售卖机可以增加利润,但是我们不应该这么干,因为学生们喝饮料不健康。
推理:本题的前提和结论讨论的是不同的事件,并且结论是果。
顺序的因果逻辑:因为学生们喝饮料不健康,所以我们不应该放一个饮料自动售卖机
(因)前提:学生们喝饮料不健康
(果)结论:我们不应该放一个饮料自动售卖机
选题方式:因果推理只有一个评估方向,简而言之,即(由于本题问的是假设,所以答案选项需在“取非”后满足),反驳推理文段中的结论。
选项分析:
A选项:Correct. 如果在食堂放置一个饮料售卖机,那么学生们最终会消耗更多的软饮料。若放置一个饮料售卖机也不会导致学生们多买饮料,则本选项必然可以反驳结论。
B选项:现在学生们在学校消耗的饮料数量并不会对他们的身体有害。无论现在消耗的量是否有害,都不能反驳放了饮料机后是否会有害。
C选项:如果学生们根本不喝饮料的话,那么他们将会比偶尔喝一点的人更加健康。本选项和售卖机其实没有关系,如果建立了售卖机,学生们就不是偶尔喝的问题了。
D选项:如果售卖机不建立,学生们不会从家带饮料来。就算是有些学生会带一些饮料来,那么增加一个售卖机至少会让一些学生多买饮料。
E选项:学校主要的关心应该是让它的学生拥有良好的健康。本选项和方案无关,主要讨论的是方案的目的。
要加强的推理是:放贩卖机会使得学生多喝饮料。
其他的什么学校的态度E、学生现在饮料喝的多少B、喝饮料对身体健康的影响C、学生自己带不带饮料都没关系,主要是关注从贩卖机里边出来的饮料销量多不多。
