Explain the main points of this excerpt in a brief summary:  The Great Barrier Reef is the world's largest coral reef system, comprising over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometers (1,400 mi) over an area of approximately 344,400 square kilometers (133,000 sq mi). The reef is located in the Coral Sea, off the coast of Queensland, Australia. It can be seen from outer space and is the world's biggest single structure made by living organisms. This reef structure is composed of and built by billions of tiny organisms, known as coral polyps. It supports a wide diversity of life and was selected as a World Heritage Site in 1981.

Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: In short, what does creating zones do for a home? Use this text:

 Jenny Davis
Native New Yorker and designer Jenny Davis knows a thing or two about small space living is her thing, learning make her home work for her growing family.

"Creating zones within a room can make it look and feel bigger, as long as it’s done right," she says. "Placing furniture perpendicular to or off the wall is a great way to do this. I’ve used this tactic in our kids’ bedroom where I floated a table in the back of the room to define and anchor the art area. And, in the living room, I use a toy hub to divide the kids’ play area and our living room, and it has an open back so it doesn’t minimize light or how far the eye can see.

Davis says that creating zones can help you make the most of your space, no matter the size, as well as making your home look and feel bigger.
Response: Creating zones can utilize the space for different needs and make the room feel bigger.

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.
