Multiple Choice

Approximately how long is the Great Barrier Reef chain?

Explanation:
Think about the scale of a coastline feature. The Great Barrier Reef runs along Australia’s northeast coast from near Cape York down to around Bundaberg, covering roughly 2,000 kilometers. That converts to about 1,250 miles. So the closest estimate among the choices is about 1,250 miles. The other numbers don’t match the known extent: 800 miles is noticeably shorter than the reef’s actual span, while 2,200 and 3,000 miles would exceed its typical measured length.
