Extractive summarization selects important sentences or phrases from the original text to form the summary. It is simpler and preserves the original language, but can result in less coherent summaries. Abstractive summarization generates entirely new sentences to convey the main ideas, allowing for more concise and fluent summaries. However, it is more complex and can introduce inaccuracies or omit important details. Extractive methods are more suitable for shorter texts and when verbatim preservation is crucial, while abstractive approaches are better for longer texts and when more concise and natural language is desired. The choice depends on the specific use case and requirements.

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: Can you give me a tl;dr of the main social media platforms? 

Social media refers to the means of interactions among people in which they create, share, and/or exchange information and ideas in virtual communities and networks. The Office of Communications and Marketing manages the main Facebook, Twitter, Instagram, LinkedIn and YouTube accounts.
Response: Here are the main social media platforms: Facebook, Twitter, Instagram, LinkedIn, and YouTube.

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.
