There are two main types of summarization techniques: extractive and abstractive. Extractive summarization involves identifying and extracting the most important sentences or phrases from the original text and combining them to form a summary. This method retains the original wording and phrasing, making it more suitable for factual texts. Abstractive summarization, on the other hand, goes beyond mere extraction and aims to generate entirely new sentences that capture the central concepts and ideas of the source material. This approach involves understanding the text's meaning, interpreting the information, and rephrasing it in a concise and coherent manner. Abstractive summarization is more challenging but can produce more natural-sounding and fluent summaries, especially for subjective or creative texts.

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: In a few sentences, explain investing using this:

Investing
Investing involves purchasing assets, usually stocks and bonds, to earn a return on the money invested. Investing aims to increase an individual's wealth beyond the amount they invested. Investing does come with risks, as not all assets appreciate and can incur a loss.

Investing can be difficult for those unfamiliar with it—it helps to dedicate some time to gain an understanding through readings and studying. If you don't have time, you might benefit from hiring a professional to help you invest your money.
Response: Investing is the buying of assets, such as stocks and bonds, to increase money over time. It comes with risks, but taking time to understand the process or hiring a professional can make it less difficult.

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.
