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 the myth busted by this text.

Myth 8: 90 Percent of Fights Go to the Ground
This is often passed around in grappling arts and it is based on a study of law enforcement. What happens between the police and the people they are fighting isn’t what happens on the street day-to-day. There is a more updated study that shows about half of fights going to the ground. However, that study is based on CCTV footage so we don’t know how many of those people were compromised by drugs or alcohol. I was a high school teacher for years and I seldom saw hallway fights go to the ground. Did some? Yes. But not often. All that can be said for certain is that, in a fight, going to the ground is definitely a possibility.
Response: There is a myth that 90 percent of fights go to the ground. An updated study shows this only happens in about half of fights.

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.
