问题 From the beginning of the text, we can learn that
The most important reason why DTVs sell less than traditional sets is that

选项 A、people are reluctant to abandon their old TV sets.
B、the traditional sets are much cheaper than DTVs.
C、the DTV retailers always close their doors at an early time.
D、people have been used to watching traditional analog TVs.

答案B

解析 细节题。从文中第八段可以看出,当数字电视机上个世纪末刚刚上市的时候,价格通常都是几千美元,因此让很多消费者望而却步。由此可知,数字电视机的销量不如传统模拟电视机的最重要的原因应是"传统电视机要比数字电视机便宜得多"。其他三项都不是文章中提及的最重要的原因。
