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.

Instruction: Please summarize the main points of these paragraphs in a couple of sentences.

Last month, Elon Musk announced his vision for Tesla and a sustainable future, but was vague on specifics. On Wednesday, the company laid out in detail the math behind his so-called Master Plan 3 including what the economy at large might look like in a greener future and how much it would cost compared to the alternative.

Tesla’s report finds that an economy built on sustainable energy is not only feasible, it is economically preferable. The switch would require “less investment and less material extraction than continuing today’s unsustainable energy economy,” Tesla found. The investment needed to develop a sustainable economy—based on an electrical grid and manufacturing industry powered by renewable energy and electrified transportation—would be $10 trillion, but sticking to oil, coal, and natural gas would end up costing $14 trillion globally over the next two decades, according to the paper, a difference in price roughly equivalent to the annual GDP of Germany.
Response: While laying out the details of his Master Plan 3, Elon Musk noted that an economy built on sustainable energy is preferable to one that isn't. It would be a $10 trillion global investment over the next 20 years to be powered by renewable energy compared to  a $14 million investment to maintain existing energy sources.

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.
