题目：

In the year following an eight-cent increase in the federal tax on a pack of cigarettes, sales of cigarettes fell ten percent.  In contrast, in the year prior to the tax increase, sales had fallen one percent.  The volume of cigarette sales is therefore strongly related to the after-tax price of a pack of cigarettes.
 
The argument above requires which of following assumptions?

A、During the year following the tax increase, the pretax price of a pack of cigarettes did not increase by as much as it had during the year prior to the tax increase.
B、The one percent fall in cigarette sales in the year prior to tax increase was due to a smaller tax increase.

D、For the year following the tax increase, the pretax price of a pack of cigarettes was not eight or more cents lower than it had been the previous year.

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。
