可能使我脑子转不过弯，可我觉得23的A也对啊。 However, although aluminum recycling was more widely practiced in this period than glass recycling, it was found that the weight of glass bottles in household garbage declined by a greater percentage than the weight of aluminum cans.

既然玻璃比较重回收的少也会占大的比例吧，我理解的哪里有问题么？nn点拨一下的撒

我明白版主的意思，是说数量上的差别。但(A) Glass bottles are significantly heavier than aluminum cans of comparable size. 他这么一说我就觉得数量问题应该可以忽略吧。另外，这一项里强调了of comparable size，我不觉得有什么必要，难道是这里有陷阱？
    

我也觉得C是对的，就是没明白A为什么不对
