To lay cable to remote areas would be prohibitively expensive since the number of customers served by such cable lines would be too small for the cable company to make a profit. Microwave cable service is a good alternative for use in remote areas because the signal is sent through the air and cables are unnecessary. However, microwave cable service should not become standard practice in non-remote areas, because the long-term effects of microwaves are not known.Which of the following is the best conclusion to the statements above:
a:Microwave technology should be regulated by the government indefinitely.
b:Residents of remote areas must take precautions to mitigate the potential danger of microwaves.
c:Most residents of non-remote areas will not want to change their existing service to microwave service.
d:Microwave cable service is safe enough for use in remote areas.
e:Microwaves are potentially more dangerous in urban areas than in suburban areas作者: isuffering 时间: 2003-3-26 21:56
