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: Write a short summary of the passage.

This is the passage:
The most famous description of Valhalla in Old Norse literature, that of Grímnismál, portrays it as being located in Asgard, the gods’ celestial fortress.

However, other lines of evidence suggest that it was at least sometimes seen as being located underground, like the more general underworld.
Response: Grímnismál is the most famous portrayal of Valhalla, locating it in Asgard, but other theories say it was underground.

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 these instructions on writing a summary:

To write an effective summary, start by carefully reading the source material to fully understand its content and identify the main idea or central argument. Take notes on key points, explanations, and evidence as you read. Set aside any opinions or reactions of your own. When drafting the summary, focus solely on restating the essential information from the original text. Begin with a topic sentence that clearly states the main idea or argument. Then, concisely paraphrase the key points and supporting details in your own words. Present the information objectively and logically. Omit examples, redundancies, or minor details that aren't crucial to the overall meaning. Use clear, straightforward language to explain the core concepts in a condensed way. Avoid copying full sentences or quotes from the source.
