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: Source text:
At its simplest, forex trading is similar to the currency exchange you may do while traveling abroad: A trader buys one currency and sells another, and the exchange rate constantly fluctuates based on supply and demand.

Currencies are traded in the foreign exchange market, a global marketplace that’s open 24 hours a day Monday through Friday. All forex trading is conducted over the counter (OTC), meaning there’s no physical exchange (as there is for stocks) and a global network of banks and other financial institutions oversee the market (instead of a central exchange, like the New York Stock Exchange).

A vast majority of trade activity in the forex market occurs between institutional traders, such as people who work for banks, fund managers and multinational corporations. These traders don’t necessarily intend to take physical possession of the currencies themselves; they may simply be speculating about or hedging against future exchange rate fluctuations.

A forex trader might buy U.S. dollars (and sell euros), for example, if she believes the dollar will strengthen in value and therefore be able to buy more euros in the future. Meanwhile, an American company with European operations could use the forex market as a hedge in the event the euro weakens, meaning the value of their income earned there falls.

Summarization request:
Briefly summarize how forex trading works and who the major players are.
Response: Forex trading involves exchanging one currency for another. The value of currencies fluctuates constantly based on supply and demand as well as economic factors. Most forex trading is done between large institutions like banks, fund managers, and multinational companies. These major players speculate on the strength of currencies or hedge against changes. They don’t usually take physical possession of the currencies.

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 precise summary of a longer piece of text. It involves identifying the key points and essential information in the original text and presenting them in a condensed format that captures the essence of the content. The goal of summarization is to convey the main ideas in a clear and coherent manner while eliminating redundant or extraneous details.

There are two main types of text summarization: extractive and abstractive. Extractive summarization selects and reproduces the most important sentences or phrases from the original text, while abstractive summarization generates new, concise sentences that capture the meaning of the source material.

Text summarization has numerous applications, including:

1. Document analysis and information retrieval: Summaries allow users to quickly grasp the essence of lengthy documents, making it easier to identify relevant information and decide whether to read the full text.

2. News and article summarization: News agencies and content aggregators use summarization to provide readers with concise overviews of articles and stories, allowing them to stay informed without having to read every article in its entirety.

3. Academic research and literature reviews: Researchers can use summaries to quickly comprehend the key findings and contributions of various academic papers, facilitating literature reviews and identifying relevant studies.

4. Meeting minutes and report summaries: Summarization can be used to create concise summaries of meetings, presentations, or reports, highlighting the most important points and decisions made.

5. Text simplification and accessibility: Summaries can help make complex or technical information more accessible to a broader audience by presenting the essential ideas in a simplified and easily understandable format.
