What are the examples of a summary lead?

A summary lead provides the essential information of a news story in a concise manner. For example, "A powerful earthquake struck the city at 3 PM today, causing widespread damage and at least 20 injuries." Another example is, "The local school board voted unanimously to implement a new curriculum aimed at improving student performance." These leads quickly inform readers of the who, what, where, when, and why of the story.
