1. the average number of Sunday papers sold by the company was81,000 less than
2. on average, the number of Sunday papers sold by the company was81,000 less than it was
3. the company sold an average of 81,000 fewer Sunday papers than in
4. the company averaged sales of 81,000 fewer Sunday papers thanwhat it did in
5. the average sale of Sunday papers for the company was 81,000 lessthan what they were in

请问正确答案3中，为什么是把少卖了多少份和去年的时间对比呀？
我觉得，相比之下，4除了averaged不对，后面的what it did in更适合和卖出的动作对比，更能体现平行呀？

4改变了原意，重心转移，所以不对
3 是与In the six-month period that ended on Sept. 30期间售卖的量对比，没错
供参考。
