问题 In a 21st-century workplace,what is used by the boss to monitor his employees’ computers?
NetVizor can create a copy of what the employee is seeing by catching ______.
选项
答案a snapshot of a computer screen
解析 根据题干中的what the employee is seeing定位到第四段末句It can even capture a snapshot of a computer screen, providing an employer with a replica of what the employee is seeing on his or her monitor．此处应填入名词性成分，作catching的宾语。题目问的是监控软件NetVizor可以通过抓取什么来对员工浏览的内容进行备份。文中第四段末句指出，NetVizor可以捕获员工电脑的截屏图像，从而给雇主提供一个虽工浏览内容的备份，题干中的copy与原文中的replica对应，均为“备份，复制品”之意，catching与capture对应，意为“抓取，捕获”，因此答案应为文中capture后面的名词短语a snapshot of a computer screen。
