A bird flu, a massive earthquake, a monster storm and a terrorist attack are all threats to major cities in the U.S.
Incompatible communications is a country-wide problem in the U.S. because of the ______ which should be converted or replaced.
选项
答案
decades-old radio systems。
解析
根据题干中的信息词incompatible communications和converted 定位到第三个小标题下的第一段,可知通信不畅是全国(美国)性的问题,而修整或更换已使用数十年的无线电系统既费时又费钱,由此推断,通信不畅的原因是无线电系统年久失修,因此可得答案。
