希望有人来指点指点，这道题我把自己的思考写在了上面，但是不知道分析得对否

The average hourly wage of television assemblers in Vernland has long been significantly lower than that in neighboring Borodia.  Since Borodia dropped all tariffs on Vernlandian televisions three years ago, the number of televisions sold annually in Borodia has not changed.  However, recent statistics show a drop in the number of television assemblers in Borodia.  Therefore, updated trade statistics will probably indicate that the number of televisions Borodia imports annually from Vernland has increased.
Which of the following is an assumption on which the argument depends?
{{{{{分析： 背景：V国组装电视工人的工资比B的低（V国电视机价格应该比B过便宜），
                   尽管， B国把V国电视机的关税降低了，B国的电视机销量没有上升（这句话只是告诉我们，V国电视和B国电视的销量没有同时上升)，但是最近的数据显示B国的电视组装工人数减少了（B国自产的电视机需求因价格不占优势而销量减少），所以，这个数据告诉我们B过向V国进口的电视机数量增加了。
        （ 背景的提出只是对since 后的那个条件加强，它不单独构成大的影响）
Premise:price of V television is lower than B teleision
           The number of television assemblers dropped in B
Conclusion:the number of tv B imports from V has increased}}}}}}
A.The number of television assemblers in Vernland has increased by at least as much as the number of television assemblers in Borodia has decreased.无关比较
B.Televisions assembled in Vernland have features that televisions assembled in Borodia do not have.无关比较
C.The average number of hours it takes a Borodian television assembler to assemble a television has not decreased significantly during the past three years.正解，取非削弱
D.The number of televisions assembled annually in Vernland has increased significantly during the past three years.无关
E.The difference between the hourly wage of television assemblers in Vernland and the hourly wage of television assemblers in Borodia is likely to decrease in the next few years.削弱，时间朝向也不对


以前没接触过herl的方法，有童鞋能够是示范一下，这道题怎么用CQ解吗？？看了herl笔记整理的帖子还是不太明白怎么用herl逻辑解题
