The Great Barrier Reef, located off the coast of Queensland, Australia, is the world's largest coral reef system. It stretches over 2,300 kilometers and covers an area of approximately 344,400 square kilometers. The reef is composed of over 2,900 individual reefs and 900 islands. It is home to thousands of species, including 1,500 species of fish, 400 species of coral, and 4,000 species of mollusks. The Great Barrier Reef is visible from space and was designated a UNESCO World Heritage Site in 1981.
According to the passage, how many individual reefs make up the Great Barrier Reef?
- Over 1,500 reefs with fish species
- Approximately 2,300 reefs across kilometers
- Over 2,900 individual reefs (correct answer)
- About 4,000 reefs with mollusk species
Explanation: The passage states that the reef 'is composed of over 2,900 individual reefs and 900 islands.' Choice A confuses the number of reefs with fish species. Choice B confuses the number of reefs with the length measurement. Choice D confuses the number of reefs with mollusk species.
