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.

Describe the different types of summaries that can be generated, and provide examples of when each type might be useful.

There are several types of summaries that can be generated, each serving different purposes and contexts. Extractive summaries involve selecting and presenting the most important sentences or passages from the original text verbatim. These are useful for quickly grasping the key points without altering the original wording, such as in news article previews or research paper abstracts. Abstractive summaries, on the other hand, involve paraphrasing and synthesizing the main ideas in the summarizer's own words, providing a more concise and coherent summary. These are helpful for condensing complex information into a clear, standalone summary, like executive reports or literature reviews. Query-based summaries are tailored to specific questions or topics, highlighting relevant information from the text to answer the query. These are valuable for focused information retrieval or question-answering systems. Finally, update summaries track and summarize changes or new information added to a document over time, useful for monitoring evolving situations or tracking revisions in collaborative writing projects.
