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.

Summarize the following paragraph in 2-3 sentences: Anecdotal evidence suggests that exercise can reduce stress, anxiety, and depression. Regular physical activity can boost self-esteem and improve sleep quality. It can also increase energy levels and cognitive function. Exercise releases endorphins, which are the body's natural mood-boosters. Studies have shown that even a single bout of exercise can improve mood and reduce symptoms of depression and anxiety.

Exercise is believed to reduce stress, anxiety, and depression, and boost self-esteem, sleep quality, energy levels, and cognitive function. It releases endorphins that improve mood, and studies show even a single session can alleviate symptoms of depression and anxiety.
