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: I want a one-sentence summary of this text.

This invasive species releases chemicals that prevent other plants from growing. And it is taking over native landscapes across the eastern United States. It looks a lot like round-headed bushclover, a close relative that’s native to the United States. Even for people who are trained to tell the difference, it’s easy to miss these shorter plants in the sea of tall grasses.
Response: The invasive species, which looks similar to the U.S.'s native round-headed bushclover, releases chemicals that stop other plants' growth. 

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.
