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: What does this article say about ham? Write one sentence for each paragraph only.

Ham is pork from a leg cut that has been preserved by wet or dry curing, with or without smoking.[1] As a processed meat, the term "ham" includes both whole cuts of meat and ones that have been mechanically formed.

Ham is made around the world, including a number of regional specialties, such as Westphalian ham and some varieties of Spanish jamón. In addition, numerous ham products have specific geographical naming protection, such as prosciutto di Parma in Europe, and Smithfield ham in the US.


Response: Ham is a cured product made from a cut pork leg. It is produced worldwide and several regions have unique versions, such as the Smithfield ham from the United States, and Westphalian ham.

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.
