单选题 Traditionally, garbage is thought to be ______.

A、 a worthless burden to big cities
B、 something that can be reused
C、 a raw material for making new products
D、 able to be recycled but difficult to handle

【正确答案】 A

【答案解析】本题为推理题。第一段中讲到“The traditional way of getting rid of solid wastes is quickly becoming inadequate”(传统处理方法是把固体垃圾扔了，这种方法很快就不合时宜了)。由此可推知，传统的方法是把垃圾扔了，认为垃圾是没有价值的。
