Which of the following was NOT an effect of the change in business procedures？( )

A.An increase in credit sales.
B.The use of courier services between cities.
C.The adoption of simpler accounting procedures.
D.The improvement of roads.

答案：C
解析：
细节题。根据题干关键词effect，the change定位到文章第二段。题干中出现大写EXCEPT/NOT等明显表示否定的词时，要求选出与原文事实信息不符的选项，属于否定事实信息题。本题可根据文章第二段内容逐一排除。A项“赊销的增长”与第二段最后一句话相对应，该商业城市间兴起常规的快递服务指出商人之间互相信任促进了赊销的增长。B项“城市之间使用快递服务”与第二段第二句对应，即商业城市之间常规的快递服务开始兴起。C项“采用更简单的会计程序”与原文第二段第三句中Commercial accounting became more complex的表述不符。第二段倒数第二句指出公路收费变高，能为道路改革提供资金，因此D项“改善了道路状况”符合原文。
