Kevin is writing a column for the science section of his community newspaper on how cell phone technology works. Here’s an excerpt: To avoid being taken advantage of by cell phone providers, it is essential that consumers understand how their devices work. Cell phones work very much like radios. In fact, before the invention of the telephone, radios provided a similar sense of connection across distances. Cities are divided into areas, or “cells,” each equipped with a base station. When you turn on a cell phone, it automatically connects to the nearest base station, even if you’re not making a call. Which of the evidence that Kevin has presented is irrelevant?
