问题 In 1948, people living in remote areas could see TV programs by ______ in the United States.
What’s the purpose of the manufacturers’ adding a switch to most new television sets?
选项 A、To make more money.
B、To spread the cable system.
C、To make ordinary viewing possible.
D、To adapt to the new development of the cable system.
答案D
解析 本题涉及到电视生产商为大多数新电视增加适配器的目的。该段首句提到，随着社区有线电视站的增加和有线系统的范围扩大，电视生产商不得不给新电视增加适配器，这样用户就能调节频道，生产商这样做是随着有线电缆的发展而调整策略的，所以目的是为了适应电缆系统的新发展，故答案为[D]。
