@Tina老师,老师我主要想问您一下C和E选项。C选项的claim是只表示观点的意思不能指事实么?E选项我排除是因为后半部分。conclusion about a predicted bad effect of the policy. 是怎么理解鸭,B2是批评critics的。我觉得critics是说的关于这个政策的坏影响(不好的地方)。所以把E排除了。麻烦老师帮忙解答。
If 500 is the mutiple of 100 that is closest to x and 400 is the multiple of 100 that is closest to y,which multiple of 100 is closest to x+y? (1)x小于500 (2)y小于400
