Study the following text carefully:

Text summarization aims to capture the most salient information in a source text and present it in a condensed form. This is useful for quickly understanding large volumes of textual data. Extractive summarization methods work by identifying and extracting the most important sentences or phrases from the input text to create summaries. In contrast, abstractive summarization techniques aim to produce summaries by interpreting the semantic meaning of the source text and then generating new sentences that convey the key points. Both approaches have their own advantages and challenges. Extractive methods are generally simpler to develop but can sometimes produce incoherent summaries. Abstractive techniques can generate more coherent and concise summaries but require more complex natural language generation capabilities. The choice between extractive and abstractive summarization depends on the specific requirements of the application, such as the desired summary length, the need for grammaticality and coherence, and the computational resources available.

Please summarize the key information about extractive and abstractive summarization covered in the text.

The text discusses two main approaches to text summarization: extractive and abstractive. Extractive summarization involves identifying and extracting the most important sentences or phrases from the source text to create summaries. Abstractive summarization, on the other hand, aims to generate new sentences that capture the key semantic meaning of the source text. While extractive methods are simpler, they may produce incoherent summaries. Abstractive techniques can generate more coherent and concise summaries but require more complex natural language generation capabilities. The choice depends on factors like desired summary length, need for grammaticality, and available computational resources.

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: Read the following: 

If a Spanish class were to go on an in-country immersion in Spain, they’d be flooded by the sights and sounds of native speakers going about their business. Good times! But that would make a huge dent in everybody’s budget. So why not bring a native speaker to class instead?

Pick somebody who’s outgoing, a natural extrovert who loves interacting with people and doesn’t take himself too seriously. Ask him to prepare a short talk. And he can really talk about anything—so long as he does it in Spanish. He can tell his personal story, talk about his job or share some interesting quirk about his culture.

You may be a native speaker yourself, but count yourself out. Bring some new face to stand in front of the class. (There’s just something more effective about a fresh face.)

Now, please summarize what it says about having a native speaker visit the classroom.
Response: Bringing a native speaker into the classroom can help immerse students in a foreign language. Invite a guest speaker who is outgoing, extroverted, and has something interesting to share. 

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.
