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: Give me a three sentence summary of the following document.

Here’s that document:
The mountaineering athlete said that after about 65 days, she stopped trying to keep track of how long she had been in the cave, and had guessed she was underground for about 160 to 170 days when her team came to get her. While not officially confirmed by Guinness, her team believes the 500 days is the world record for voluntary time living in a cave.

Of course, living in a cave for 500 days isn't without its difficulties. At one point, Flamini was covered by flies after an invasion. She also dealt with auditory hallucinations. "You are silent, and the brain makes it up," she says.

There was one other hiccup—a purely above-world technical challenge with the router relaying audio and video of her cave experience to the team. The router went out and the fix required that she move out of the cave into a tent, remaining in isolation for the eight-day process.

The cave adventure has given scientists the opportunity to study everything from social changes—such as time perception and disorientation—to physical changes in brain patterns and sleep.
Response: Flamini, a mountaineering athlete, spent 500 days living in a cave voluntarily, which her team believes to be a Guinness world record. The difficulties she faced included being covered with flies and auditory hallucinations. At one point, she had to emerge and spend 8 days in a tent after the router relaying information to her team went out.

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.
