You are a student taking an online course on summarization techniques. The following text is an excerpt from one of your course readings. Summarize the key points made in the passage:

Extractive summarization focuses on identifying and extracting the most salient sentences or phrases from the original text to form a summary. This approach is commonly used for tasks such as news article summarization, where the goal is to provide a concise overview of the main events or topics discussed. Extractive methods rely on features like word and phrase frequency, position in the text, and linguistic cues to determine the most important content. Abstractive summarization, on the other hand, aims to generate entirely new sentences that capture the essence of the original text. This approach is more challenging as it requires understanding the semantics and generating coherent, fluent text. Abstractive summarization is often employed in scenarios where a rewritten summary is preferred, such as for long documents or technical reports.

The passage discusses two main approaches to text summarization: extractive and abstractive. Extractive summarization identifies and extracts the most important sentences or phrases from the original text to form a summary, commonly used for tasks like news article summarization. Abstractive summarization generates new sentences that capture the essence of the text, often used when a rewritten summary is preferred for long or technical documents.

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.
