og 41，没有人问过

讲市长的bus services计划的。答案没问题，只是D。

D）The number of buses entering the midtown area of Greenville during the morning hours is exactly the same now as it was one year ago.

公共汽车数量在本题是无关项。但OG的解释：An alternative explanation based on the running of more buses can be eliminated. 意思是原文已有关于汽车数量已经增多的描述，所以D不对，因为跟原文给的条件相反。

但原文中看着有点关系的句子只是：the mayor's publicity campaign for Greenville's bus service began six months. 哪里有说“汽车数量已经增多”呢？

谢谢。
