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: Given the following article, write a summary of the key ideas.

This is the article:
Despite the city’s support, the number of farms in Tokyo has been slowly declining for years, by nearly 14.5 percent between 2005 and 2015. Over the same period, the average age of Tokyo’s farmers increased by 3.3 years, to nearly 64. Today, Ryoto Matsuzawa says there are 1,250 farms left, most of which are under one hectare in size. “We want to preserve those at all costs.”

The city recently made a crucial decision to do so. Eighty percent of the farms protected under the Law on Productive Green Areas were registered the year that law was enacted, in 1992. The law stipulates that after 30 years, the landowners can ask the city to buy their land at market price. But most cities, strapped for cash, can’t afford to. If they don’t, the land loses its tax subsidy and can be sold for commercial development.

In other words, about 80 percent of the farms protected under the law were eligible to come up for sale in 2022. “These areas are nearly 45 percent of the agricultural land in Tokyo,” says Ryoto Matsuzawa.
Response: Between 2005 and 2015, the number of farms in Tokyo decreased by 14.5 percent and the average age of farmers increased by 3.3 years. Preserving Tokyo's remaining 1,250 small farms feels priceless to many, but there is an ongoing issue where many cities cannot afford to buy the land protected under the Productive Green Areas Law at market value, as legally required. This leads to the land being lost for agricultural use, and usually being sold for commercial development.

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.
