Explanation
A landmark is anything that helps you know where you are — in space, in time, in history. If you’re sailing from Europe to New York, the Statue of Liberty will be the landmark that lets you know you’re in the right port. If you’re walking to your cousin’s house, the pizza shop on the corner is the landmark that lets you know you just have two blocks to go. Getting your driver’s license is a landmark event, as was the Revolutionary War — though which battle was harder is yours to determine.
