Extractive summarization involves selecting and concatenating the most important sentences or phrases from the original text to form the summary. For example, given the text 'The sun is a star at the center of our solar system. It is a nearly perfect sphere of hot plasma and is the most important source of energy for life on Earth. The sun has a diameter of about 1.39 million kilometers.', an extractive summary could be: 'The sun is a star at the center of our solar system. It is the most important source of energy for life on Earth.' Abstractive summarization involves generating new sentences to capture the core meaning of the text, often using advanced natural language processing techniques. For example, an abstractive summary of the same text could be: 'The sun, a hot plasma sphere approximately 1.39 million kilometers in diameter, is the central star in our solar system and the primary energy source for life on Earth.'

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: Summarize this information in two sentences. 

After a decade of exploring the surface of the Red Planet, the Curiosity rover has recently been looking up. On February 2, 2023, the NASA rover captured a stunning sunset on Mars. The image shows rays of sunlight stretching across the horizon, lighting up a mass of clouds.

"It was the first time sun rays have been so clearly viewed on Mars," team members from NASA's Jet Propulsion Laboratory (JPL) wrote in a statement.

The sun rays captured in the image are also known as crepuscular rays. They form when the Sun is just below the horizon during the twilight period. This could be either at sunrise or sunset.
Response: On February 2, 2023, a decade after exploring Mars' surface, NASA's Curiosity rover took a picture of a sunset on Mars. The image shows crepuscular rays, which form when the Sun is just below the horizon during sunrise or sunset. 

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.
