Extractive summarization involves selecting and concatenating the most important sentences or phrases from the original text to create a summary. For example, given the text: 'The cat sat on the mat. The dog chased the cat. The cat climbed a tree to escape the dog.', an extractive summary could be: 'The cat sat on the mat. The dog chased the cat. The cat climbed a tree.' Abstractive summarization, on the other hand, involves rephrasing and generating new sentences that capture the key ideas of the text. For the same example, an abstractive summary could be: 'A cat was chased by a dog and had to climb a tree to escape.'

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: What are the main points of this science article?

Our lunar neighbor has inspired stories since the first humans looked up at the sky and saw its gray, cratered surface. Some observers saw among the craters the shape of a person's face, so stories refer to a mysterious "man in the Moon." Hungrier observers compared the craters to cheese and dreamed of an entire sphere made of delicious dairy products.

The Moon made its film debut in a 1902 black and white silent French film called "Le Voyage Dans la Lune" ("A Trip to the Moon"). And a year before astronauts walked on the Moon, "2001: A Space Odyssey" (1968) told the story of astronauts on an outpost on the Moon. Decades later, it is still widely regarded as one of the best science fiction movies ever made.
Response: The Moon has been inspiring stories for a long time, with people even seeing faces in its craters and comparing it to cheese. The French silent film "Le Voyage Dans la Lune" (1902) was the first to include the Moon, and "2001: A Space Odyssey" (1968) also featured the Moon. 

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.
