问题 Because short messaging service is a kind of data communication, second generation wireless cannot support it.
If many people have demand for the network at the same time, the data communication will be difficult even with 4G technology.
选项
答案N。
解析 由题干中的demand定位到第一个小标题下第四段第四句As people congregate and create pockets of high demand, they also create additional routes for each other, thus enabling additional access to network capacity.题干中的many people have demand for the network at the same time与原文中As people congregate属同义转述；但是原文提到，这时通过4G技术可以增加网络的容量而不会出现通信困难。故题干与原文描述不符。
