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 why Samsung Smart TV’s private listening feature is better than using Bluetooth. 

Samsung Smart TV allows you to use your phone for private listening
If you’ve ever wanted to watch TV without disturbing anyone else, you know that sometimes private listening though headphones can come in handy. Samsung smart TVs have a feature that makes that much, much easier.

Sure, some smart TVs with Bluetooth built in can connect to a pair of headphones. But not all headphones allow for multiple pairings, and switching back and forth between devices can be a pain. Instead, Samsung allows you to use your smartphone and its existing headphone setup.

Via the SmartThings home automation app, you can connect to your TV and select “Play TV sound on phone.” Then, just use the headphones of your choice to listen to your programming, free from the worry of making too much noise.

Response: Samsung Smart TV’s private listening feature, used via the SmartThings app, is better than a standard Bluetooth connection because not all headphones allow for multiple pairings, and switching between devices can be annoying. The feature allows users to stream through the existing setup on their smartphones. 

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.

Regular exercise is beneficial for maintaining good health because it enhances cardiovascular fitness, strengthens muscles and bones, and helps control weight. It also improves mental health by reducing stress, anxiety, and depression. Additionally, regular physical activity can boost the immune system, improve sleep quality, and reduce the risk of chronic diseases such as diabetes and heart disease.
