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: Hello. What are the key points of how cars are getting more fuel efficient in the following article? Summarize this in about 2 sentences per paragraph for me, please.

A big factor in fuel efficiency is the type of fuel that cars use. While you may be used to premium, regular, and diesel, you may have noticed the sticker at your local gas station that says that 10% of the gasoline you’re purchasing is ethanol. Ethanol is a type of fuel made from corn that can be burned in a regular combustion engine without producing the harmful pollution that gasoline is known for. While ethanol may not bring the price of gas down much, it does burn better than gasoline, at least to some extent, and has contributed to better fuel efficiency in modern vehicles.

Anyone who owns a hybrid car can understand how much gas can be saved by switching to an electric motor. While vehicles that depend completely on an electric motor aren’t very powerful and need to be recharged regularly, a hybrid vehicle that combines the efficiency of an electric motor with the raw power produced by a combustion engine can save drivers a ton of gas without a significant loss in performance.

Another way that cars are becoming more fuel efficient has to do with how cars are being built. While older vehicles were made of steel, newer vehicles are made of aluminum, fiber glass, and even ceramic materials. By reducing the total amount of weight that a combustion engine or hybrid motor has to move, newer vehicles are able to get better gas mileage and tend to have more reliable engines.
Response: The first key point is that gasoline now contains 10% ethanol. The gasoline-ethanol mixture burns more efficiently than gasoline alone and produces less pollution, which makes cars more fuel efficient. 

The second key point is that putting electric motors in cars makes them considerably more fuel efficient and significantly reduces pollution. Hybrid cars give drivers the best of both worlds by combining the horsepower found in gas-powered engines with the higher fuel efficiency and reduced pollution of electric motors. 

The third key point is that cars are now being built with lighter materials such as aluminum and fiberglass instead of heavy steel. The cars weigh less so they get better gas mileage and produce less pollution.

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.

Hey. I'm looking at an article about the importance of sleep for overall health. Could you summarize the key points made in the article in a few sentences each?
user
One key point is that sufficient sleep is crucial for cognitive function, as it enhances memory, learning, and decision-making abilities. Another important point is that sleep supports physical health by aiding in muscle repair, immune function, and hormone regulation. Lastly, good sleep is vital for emotional well-being, helping to manage stress and maintain a balanced mood.
