请问一下老师,关于这道题,我是根据 either ..or..绝对的平行做对的,但是在and并列的两个谓语 date 和 were fashioned的这个部分有点困惑。为什么不是date and are fashioned 或者说 dated and were fashioned。我认为这里是在讲述一个客观事实:这个神像可以追朔到什么时期和由什么制成,应该是用一般现在时。were fashioed 是过去式的被动语态对吧?date and were fashioned感觉也不复合并列的要求。
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
