Explanation
Step 1: find the main verb — “引起了” (aroused, attracted). Step 2: ask “what caused it?” → the subject is “这个消息” (this news); news can attract attention, attention can't cause news. Step 3: the object is the noun phrase “大家的 + 注意”: a modifier with “的” always comes before its noun. Step 4: put it together as Subject + Verb + Object: “这个消息 + 引起了 + 大家的注意”. “引起……注意” is a common HSK 5 collocation (like “引起……兴趣”, “引起……重视”).
