Last year the rate of inflation was 1.2 percent, but for the current year it has been 4 percent. We can conclude that inflation is on an upward trend and the rate will be still higher next year.
Which of the following, if true, most seriously wearkens the conclusion above.
B: Last year a dip in oil prices brought inflation temporarily below its recent stable annual level of 4 percent.
D: The 1.2 percent rate of inflation last year represented a 10-year low.
抱歉没看清原来你写的,打眼一看以为全都是选项不好意思哈
按照你说的,去年是下降的,今年却上升了,那么我们完全可以认为,去年是谷底,触底反弹了,以后要开始越来越高了(an upward trend and the rate will be still higher next year)
既然结论认为越来越高,那我们直接否定他,认为它不会越来越高应该是最合适的。
B说,去年只是因为油价暴跌,所以导致通胀很低,要是油价没跌的话,通胀应该稳定在4%。
B因此说明了通胀本来就应该是4%,只是去年发生了意外,既然本来4%就是stable的,那么今年4%也就没什么好奇怪的了,更没有理由认为明年会偏离这个stable的值去变得更高!
