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 the main idea of this post about coral reefs by writing a summary sentence for me.

Pollution and a warming planet are destroying coral reefs. Here is what you can do to help.

Reduce, reuse, recycle.
(Above) Plastic and other trash are harming the ocean. Use less plastic. Recycle what you can.

Hands off!

Coral reefs are delicate. Look, but do not touch. Stepping on or touching coral can hurt it.

Use a safe sunscreen.

Sunscreen can contain chemicals that harm coral. Look for bottles marked “reef-safe.”

Fight climate change.

Walk. Bike. Reduce the greenhouse gas you produce. The planet will thank you.
Response: Climate change and pollution are hurting delicate coral reefs, but you can help protect them by recycling, biking instead of driving and using sunscreen without harmful chemicals.

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.
