Summarization is the process of shortening a text to create a coherent and fluent synthesis that captures the key information in the original text. The goal is to produce an abbreviated version of the source text by selecting and combining the most important elements. Summarization has several applications, including improving text comprehension, information retrieval, generating abstracts for research papers, and creating digests for lengthy documents. There are two main approaches to summarization: extractive and abstractive.

Extractive summarization involves selecting the most important sentences or paragraphs from the source text and concatenating them to form a summary. This method relies on selecting key components from the original text and putting them together without modifying the wording. Extractive summaries are typically shorter than the original text and preserve the most crucial information and key points.

Abstractive summarization, on the other hand, involves generating new sentences that capture the essence of the source text. This approach often involves advanced natural language processing techniques to interpret the meaning of the text, identify the main ideas, and express them using different phrasing. Abstractive summaries are typically more concise and coherent than extractive summaries, but they can also introduce inaccuracies or omit important details.

Both extractive and abstractive summarization methods can be implemented using various techniques, such as statistical methods, machine learning algorithms, and deep learning models. The choice of method depends on the specific requirements of the task, the characteristics of the input text, and the desired output format.

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.
