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 what this text says about huskies.

The Siberian husky has erect ears and eyes of brown to blue or maybe even one of each color.

The neck is carried straight and the topline is level. The well-furred tail is carried up in a sickle or sometimes straight out behind.

Siberian huskies have a very dense, plush coat with plenty of undercoat. A small ruff is found around the neck but no long fringes on the legs or tail. Color ranges from black to white and everything in-between. Most dogs do have white markings, particularly on the chest and legs.
Response: Siberian Huskies have straight necks with erect ears and brown and/or blue eyes. Their furry tails curve and their thick coats and undercoats create a ruff around their necks. They're usually black or white with white markings on the legs and chest.

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.
