Extractive summarization involves selecting and concatenating the most important sentences from the original text to form the summary. Its advantages include preserving original phrasing and factual accuracy. An example extractive summary of a news article might be: 'A major earthquake struck Indonesia today, causing widespread damage. Over 100 people are reported dead and hundreds more injured. Relief efforts are underway but have been hindered by damage to roads and bridges.' Abstractive summarization aims to understand the text's meaning and rewrite it in a concise way, potentially generating new sentences. Its advantages include increased conciseness and coherence. An abstractive summary of the same article might be: 'A powerful earthquake has devastated parts of Indonesia, leaving many dead and injured, and complicating relief operations due to infrastructure damage.' While more flexible, abstractive approaches risk introducing inaccuracies or losing important details.

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 article below:

Middle-of-funnel content

At this next stage, your target audience is now aware of your business and the solution you provide, and they’re interested.

They trust you enough to make slightly bigger commitments, like signing up for a webinar and engaging with longer-form content; and they’re interested enough in your offering to read brand-specific material like case studies, testimonials, and newsletter emails.

Their goal is to learn more about the solution you provide—both in general and the one specifically offered by your business.

Your goal is to educate them on your offering and set your business apart from competitors—not just with your features and benefits but with your expertise and knowledge.

Next, write a summary of what it says about Middle-of-funnel content
Response: Middle-of-funnel content includes brand-specific content that educates interested audiences that are already considering an offer.

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.
