(单选题)
What does the underlined part up “in the air” in Paragraph 4 mean?
A.Meaningless
B.Attractive.
C.Uncertain
D.Obvious
参考答案:C
参考解析:
细节理解题。根据第四段最后一句“Overall the answer to that is probably still up in the air,”以及上下文可知,事情没有定论。Meaningless“有意义的”;Attractive“有吸引力的”;Uncertain“不确定的”;Obvious“明显的”。所以ABD项错误。故选C。
