根据古代记录，希乐郡政府对基本商品征收的第一种税是对在希乐郡出售的每一罐食用油征税两个生丁。税务记录显示，尽管人口数量保持稳定且税法执行有力，食用油的税收额在税法生效的头两年中还是显著下降了。 下列哪一项，如果正确，最有助于解释在希乐郡油税收入的下降
A．在税法实施后的lo年，希乐郡的平均家庭收入稳定增加。
B．在食用油税实行后的两年，希乐郡政府开始在许多其他基本商品上征税。
C．在希乐郡，食用油罐传统上被用作结婚礼物，在税法实施后，食用油礼物增多了。
D．希乐郡的商品，在税法实施后开始用比以前更大的罐子售油。
参考答案：D
解析：上文的问题是：油的销售没有减少(人口数量保持稳定)也没有偷税(税法执行有力)，按罐收的油税却减少了，为什么 A项、B项为无关项；食用油多了，税收应该增加，更加不能解释题干问题，C项排除；D项指出希乐郡的商人在税法实施后，开始用比以前更大罐子售油，同样的消耗量，所用的罐数少了，所以按罐收税的油税减少了，解释了题干问题。
