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: Summarize the information about retinoids. Here is the information:
Retinoid: The term "retinoid" is a catch-all for an array of vitamin A-based products used on skin. It can treat mild fine lines and wrinkles, acne, and dark spots. It can also improve skin texture.

If you’re looking to treat uneven skin tone, dark spots, or your skin’s texture, look for the word “retinol.” It’s a type of retinoid that’s used for these purposes.

Retinol can give you younger-looking skin by speeding up new skin cell turnover, which starts to slow in your 20s.

To treat acne, dermatologists prescribe one of these retinoids – adapalene, tazarotene, tretinoin, or trifarotene. You’ll also find adapalene in an acne-fighting product available without a prescription.

When spread on acne-prone skin, a retinoid can unclog pores. This can give you clearer skin and allow other acne gels and creams to work better.

When to apply a retinoid: Dr. Baxt recommends applying a retinoid before bed. After washing your face, wait 20 to 30 minutes and then apply it.

If you find the retinoid too drying, apply a moisturizer immediately after washing your face, using a moisturizer that won’t clog your pores. Then apply the retinoid 20 to 30 minutes later.
Response: Retinoids are vitamin A-based products. They have been found to treat mild fine lines, acne, wrinkles, and dark spots and improve skin texture. Apply retinoids 20 to 30 minutes after washing your face before bed.

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.

Text summarization is the process of creating a concise and accurate summary of a longer text while preserving its key information. Summarize the following text about text summarization:

Text summarization is the task of condensing a source text into a shortened version while preserving its essential meaning and most important points. It involves identifying the key concepts, facts, and relationships within the text, and expressing them concisely without losing the overall context. The goal is to create a summary that captures the gist of the original text in a clear and coherent manner.

There are two main approaches to text summarization: extractive and abstractive. Extractive summarization selects and concatenates the most informative sentences or phrases from the source text to form the summary. Abstractive summarization, on the other hand, generates entirely new sentences that convey the main ideas of the source text in a more concise and fluent way. Abstractive summarization is more challenging as it requires understanding the text at a deeper level and generating novel language constructs.

Text summarization has numerous applications, including condensing news articles, research papers, legal documents, and customer feedback. It can help users quickly grasp the essence of long texts, saving time and effort. Automated text summarization systems rely on techniques from natural language processing, machine learning, and information retrieval to analyze the text, identify salient information, and generate coherent summaries.
