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: Can you give me a tl;dr of the following article? 

For the first time, scientists have caught a star in the act of swallowing a planet — not just a nibble or bite, but one big gulp.

Astronomers on Wednesday reported their observations of what appeared to be a gas giant around the size of Jupiter or bigger being eaten by its star. The sun-like star had been puffing up with old age for eons and finally got so big that it engulfed the close-orbiting planet.

It’s a gloomy preview of what will happen to Earth when our sun morphs into a red giant and gobbles the four inner planets.

“If it’s any consolation, this will happen in about 5 billion years,” said co-author Morgan MacLeod of the Harvard-Smithsonian Center for Astrophysics.
Response: Scientists were able to capture a star devouring a planet. The star increased in size due to old age and swallowed the nearby planet. The same will happen to Earth in 5 billion years when the sun does the same thing.

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.

Can you summarize this passage for me? The Great Wall of China, a series of fortifications made of stone, brick, tamped earth, wood, and other materials, was originally built to protect the Chinese states and empires against the invasions and raids of the various nomadic groups. It stretches over 13,000 miles and was constructed over several dynasties, starting from as early as the 7th century BC. The Great Wall is an enduring symbol of China's historical strength and perseverance.
