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: Could you summarize some facts about Stuttgart from this article?

Stuttgart is the biggest city (and capital) of the German state Baden-Württemburg. 
It’s perhaps best known as the ‘cradle of the automobile industry’, which explains why it’s home to not just one, but two car-centric museums: one belonging to Mercedes-Benz, and one to Porsche.
Besides cars though, the area around Stuttgart offers up some of the cutest small towns you can find in Germany, all easily reachable by public transport, meaning you get the best of all worlds during a visit here.
Response: Stuttgart is the capital of Baden-Württemburg and allows easy access to some of the smaller towns in Germany via public transport. The city is also home to two car museums, one belonging to Mercedes-Benz and the other to Porsche.

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.

Explain the significance of the Great Wall of China as mentioned in this passage.

The Great Wall of China is an ancient series of walls and fortifications, totaling more than 13,000 miles in length, located in northern China. Perhaps the most recognizable symbol of China and its long and vivid history, the Great Wall was originally conceived by Emperor Qin Shi Huang in the third century B.C. as a means of preventing incursions from barbarian nomads. The best-known and best-preserved section of the Great Wall was built in the 14th through 17th centuries A.D., during the Ming dynasty.
