问题 Because short messaging service is a kind of data communication, second generation wireless cannot support it. [br] With the help of 4G networks, traffic light cycle period can be adjusted according to ______.
选项
答案 demand
解析 由题干中traffic light cycle定位到第四个小标题下首段第四句This would create a traffic grid...keeping some lights green longer temporarily to improve traffic flow．此处应填入名词性成份。题干中traffic light cycle period can be adjusted与原文could change light cycle times属同义转述；题干中的according to与原文中的介词on功能相同，都表示“根据”。故空白处应填入on的宾语。
