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: Summarize this text so that a layperson could understand.

Moreover, the researchers inferred that Mars’ core is mostly made of a liquid iron alloy, with sulfur making up about 15 percent of its mass. A smattering of hydrogen, oxygen and carbon together comprise about 5 percent. The findings roughly align with some previous analyses of Martian meteorite compositions.
Response: Researchers say that Mars' core is mainly liquid iron alloy, and its mass is 15% sulfur and 5% oxygen and carbon. This matches up to past meteorite tests.

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.
