 The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometres (1,400 mi) over an area of approximately 344,400 square kilometres (133,000 sq mi). The reef is located in the Coral Sea, off the coast of Queensland, Australia. The Great Barrier Reef 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. CNN labelled it one of the seven natural wonders of the world.

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: Summarize this paragraph in 40-60 words. 

When Sebastian “Ted” Hinton was a child, his father, a Princeton mathematician, built a cubic bamboo grid in the family’s backyard to teach Hinton and his siblings to visualize space in three dimensions as they moved through the structure. But the kids were more drawn to climbing and swinging on the bars. Reflecting on this experience years later, Hinton envisioned a variant on his father’s design—a cubic metal playground frame fashioned like “a kind of forest top through which a troop of children may play in a manner somewhat similar to that of a troop of monkeys.” On October 23, 1923, Hinton—a patent attorney—was awarded the first of a series of U.S. patents for his “jungle gym,” and the monkey bars were born.
Response: Sebastian "Ted" Hinton's father built a cubic grid to help his children visualize space in three dimensions, but the kids enjoyed climbing and swinging on the bars. Hinton reflected on this childhood memory and made a variation of his father's structure, which was patented as a jungle gym on October 23, 1923. 

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.
