Text summarization techniques can be broadly classified into two categories: extractive and abstractive. Extractive summarization involves identifying and extracting the most important sentences or phrases from the original text and combining them to form a concise summary. This approach preserves the original language and structure of the text, making it suitable for scenarios where verbatim information is desired, such as summarizing news articles or legal documents. On the other hand, abstractive summarization techniques generate entirely new sentences that capture the essence of the text, often rephrasing or paraphrasing the content. These techniques leverage natural language generation models and are better suited for producing more coherent and readable summaries, particularly useful in domains like report generation or creative writing. Both extractive and abstractive techniques have their strengths and applications, with the choice depending on the specific requirements and constraints of the summarization task.

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: Write a brief summary of the main points in this text about Axiom Space's second private mission to the International Space Station.

Here's the source text:
Axiom Space is ready to launch its second-ever private mission to the International Space Station today (May 21), a flight that will mark a series of spaceflight firsts.

The 10-day Ax-2 mission to the International Space Station has been cleared for launch, representatives from Axiom Space, NASA and SpaceX said Saturday (May 20) after completing one final launch readiness review. Liftoff is set for 5:37 p.m. (2137 GMT) on a SpaceX Falcon 9 rocket and Dragon capsule, which will launch from Pad 39A of NASA's Kennedy Space Center in Cape Canaveral, Florida.

"It's obviously a very, very exciting day," Derek Hassmann, Axiom Space chief of mission integration and operations, told reporters in a teleconference this evening. "We worked a long, long time in collaboration with our partners at SpaceX and NASA to get to this point. The crew has been working very hard to get trained and they're certainly ready to go."
Response: On May 21, Axiom Space is scheduled to launch Ax-2, its second private mission to the International Space Station. Representatives from Axiom Space, NASA, and SpaceX conducted a final launch readiness review and approved the launch. The SpaceX Falcon 9 rocket and Dragon capsule are planned to launch from NASA's Kennedy Space Center in Florida. The space mission is scheduled for 10 days and involves several unprecedented events in space exploration. The mission has been planned and executed after thorough preparation and cooperation among all the parties involved.

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.
