8. The primary purpose of the passage is to
(A) present several explanations for a well-known fad
(B) suggest alternative methods for resolving a debate , . ..;~
(C) argue in favor of a controversial theory
(D) question the methodology used in a study
(E) discuss the implications of a research finding(选E)
Main idea
This question depends on understanding the passage as a whole. The first paragraph reports the findings of a recent study. The second paragraph examines possible explanations for the findings, ruling out all but one of them.
E Correct. The passage explores possible explanations for a recent research finding.
E选项里说的是implication(暗示,含义),解释里说的是explanation,觉得这两个词意思相差很大,所以觉得E选项应该把implications改成explanation才对,请大家指点一下,谢谢
第一段第一句说近来的研究提供了clue to sth.后面两句说了下这个sth.
第二段通过排除一些说法的来暗示某个说法还是比较合理的,就是那个因为牙齿跟骨头碰撞造成了teeth breakage.所以,一直是在讨论研究给的暗示(clue),而不是explanation,因为没有那么自信的语气出现过
