Read the following text carefully:

Extractive text summarization is a widely used approach in which the summary is constructed by identifying and extracting the most important sentences or phrases from the original text. This method does not generate new text; instead, it selects and concatenates the most relevant portions of the input text to form the summary.

One common technique in extractive summarization is sentence scoring, where each sentence in the input text is assigned a score based on various features, such as the presence of important keywords, sentence position, and similarity to the document's overall topic. The highest-scoring sentences are then selected and combined to form the summary.

Another popular approach is graph-based ranking, where the input text is represented as a graph with nodes representing sentences or concepts, and edges representing their relationships. Graph algorithms, such as PageRank or TextRank, are then used to rank the importance of each node, and the top-ranked sentences or concepts are selected for the summary.

Summarize the given text in approximately 65 words.

Extractive text summarization constructs summaries by identifying and extracting the most important sentences or phrases from the original text. Common techniques include sentence scoring based on features like keywords and similarity to the topic, and graph-based ranking, where sentences or concepts are represented as nodes in a graph and ranked using algorithms like PageRank.

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.
