Summarize the following passage about summarization techniques:

Text summarization is the process of creating a concise and precise summary of a longer piece of text while focusing on the main points and capturing the key information. There are two main approaches to summarization: extractive and abstractive. Extractive summarization involves identifying and extracting the most important sentences or passages from the original text and concatenating them to form the summary. This method preserves the original wording and phrasing. Abstractive summarization, on the other hand, aims to generate entirely new sentences that capture the core ideas and concepts of the text using advanced natural language processing techniques. Abstractive summaries often restructure and rephrase the content in a more concise and coherent way. Both methods have their strengths and applications, but abstractive summarization is generally considered more challenging due to the complexities involved in understanding and generating fluent natural language.

The passage explains two main techniques for summarizing text: extractive and abstractive summarization. Extractive summarization identifies and extracts the most important sentences from the original text to form the summary, while abstractive summarization generates new sentences that capture the core ideas using advanced natural language processing techniques. The passage notes that abstractive summarization is more challenging due to the complexities of natural language understanding and generation.

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 short, what does this paragraph say about cleansers? Here is the text:
A mild cleanser: When selecting a cleanser, choose one for your skin type. Dr. Katta says, “For example, if you have acne-prone skin, use a mild cleanser that removes oil.” Dry skin does better with a hydrating cleanser.

To get the best results from your cleanser, wash your face twice a day – when you get up and before bed. You also want to wash after sweating.
Response: It says to choose a cleanser based on your skin type and to wash your face before and after bed and after sweating.

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.
