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: Sum up what this says about mustard donuts. 

Just when you thought you would be hoarding mustard, thanks to a potential upcoming shortage, along comes another option for enjoying this condiment — and it’s not what you think. 

French’s Mustard is celebrating National Mustard Day (August 6) with a surprising tangy treat: the French’s Mustard Donut. Consumers nationwide can get their hands on this limited-edition snack for free this Saturday — both in-store at Brooklyn-based artisanal bakery Dough Doughnuts and nationwide online.


Created in partnership with the iconic donut shop, this mustard-flavored hole is a far cry from the condiment’s original intro in 1904 on a hot dog at St. Louis’s famous World’s Fair. But we’re not mad. The bold flavor of French’s Classic Yellow Mustard and Dough’s signature brioche recipe allows donut-devourers and mustard-lovers to come together for a reimagined classic glazed option topped with a vibrant sweet and savory mustard coating and cake crumble.
Response: The French’s Mustard company is celebrating National Mustard Day (August 6) by releasing a mustard-flavored donut, which they plan to give out limited editions of for free in some places. This is very different from its original release, but mustard lovers should enjoy it.

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.

Summarize the main points of the passage describing the history of the Eiffel Tower.

The Eiffel Tower was constructed as the entrance arch to the 1889 Exposition Universelle (World's Fair) held to celebrate the 100th anniversary of the French Revolution. Designed by engineer Gustave Eiffel, it took two years, two months, and five days to complete. Initially criticized by some of France's leading artists and intellectuals for its design, it has since become one of the most recognizable structures in the world and a symbol of France. The tower stands at 324 meters (1,063 feet) tall and was the world's tallest man-made structure until the completion of the Chrysler Building in New York in 1930. Today, the Eiffel Tower is a major tourist attraction, welcoming millions of visitors each year.
