Long-distance runners use two different kinds of cognitive strategies: “associative” and “dissociative”.associative strategies involve attending closely to physical sensations, while dissociative strategies involvemostly ignoring physical sensations. Associative strategies, unlike dissociative ones, require so much concentration that they result in mental exhaustion lasting more than a day. Since it is important for long-distance runners to enter a race mentally refreshed,---- Which one of the following most logically completes the argument?

A Long-distance runners should not rely heavily on associative strategies during training the day before they run in race

E In long-distance running, dissociative strategies are generally more effective for a day’s training run than are associative strategies

答案是A。说是要围绕associative strategies讨论才算对。
不过我觉得E更客观，因为我之前看了很多逻辑总结都说should选项过于主观不能选。而且为什么只能围绕asso strategy讨论？围绕dis 讨论反面不也是对的么？

PS。刚刚发的贴不知道怎么被删了啊= =重发一次。。。

谢谢~

嗯，是的~~谢谢！
不过should这个主观词不是一直都是看到就枪毙的类型么？

啊，好吧，THX！我跟你想的只有最后一步不同。
我想的是如果这个方法不好，就是用DA那个，所以说DA好，说A不好的选项都可以，即AE都OK。然后should排除了。。
话说should方法是溪予逻辑总结上面的。。我貌似在lawyer那边也见到过，也不是完全没道理。他们是说should的主观不符合逻辑的客观性，就像有some的基本也不能选，不符合严谨性。
