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 are Iron Man's powers? Draw your answer from the text below:

Without his suit of armor, Tony Stark has no supernatural powers. He is only limited by his imagination. Tony is a brilliant engineer and has used his talents to create a powerful suit of armor that enables the wearer to fly, shoot beams of energy from his hands and chest, and resist the vacuum of space. The suit also protects the wearer from damage and grants superhuman strength.

The suit is constantly being redesigned to face the new challenges that Tony Stark meets on a daily basis. There are specialty suits that have been made such as the Arctic, Stealth, Space, Hulkbuster, and Thorbuster armors. There have been nearly 40 different variations of the Iron Man armor in the current reality of the Iron Man comics.
Response: In short, Iron Man has no real superpowers outside his suit. Instead, he uses his engineering skillset to create armor that grants extreme strength, flight and energy beams. His suit also protects him from damage and he regularly upgrades it to meet his needs.

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.

Summarize the following passage in a clear and concise manner: 

Summarization is the process of distilling the most important information from a source text to produce an abridged version for a particular user or task. It is a widely used technique in many fields, including data processing, information retrieval, and natural language processing. Effective summarization aims to capture the essence of the original text while preserving its key points and overall meaning. Depending on the purpose and target audience, summaries can vary in length, level of detail, and writing style.

There are two main approaches to summarization: extractive and abstractive. Extractive summarization involves selecting and concatenating the most salient sentences or phrases from the source text to form a summary. This approach is generally easier to implement but may lack coherence or fail to capture the underlying meaning. Abstractive summarization, on the other hand, generates new sentences that paraphrase the key ideas of the source text. While more challenging, this method can produce more concise and fluent summaries.

Summarization techniques have numerous applications, such as generating news digests, creating executive summaries of reports, condensing product reviews, and providing concise overviews of longer documents. In the age of information overload, automated summarization tools can help users quickly grasp the most relevant information without having to read through extensive texts. However, developing effective summarization systems remains a complex challenge, requiring advanced natural language processing capabilities and a deep understanding of context and semantics.
