问题 PASSAGE TWO
Why does the author say that the task is becoming harder in Para. 7?
选项
答案Because the multiple threats to cyber-security are growing．
解析 本题考查的是网络空间安全维护任务艰巨的原因。根据题干提示定位至第七段。作者在本段第一句指出任务变得更加艰巨，并在随后一句中解释说，网络安全涉及对数据和人的双重保护，正面临多重危机，特别是网络犯罪和在线商业间谍活动都在快速发展。可见，任务艰巨的原因就是网络安全的多重威胁都在增长，故答案为Because the multiple threats to cyber—security are growing。
