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 the following guidelines for writing an effective summary: To write an effective summary, begin by reading the text thoroughly and identifying the main topic and purpose. Next, locate the key points or main ideas that support the central topic. Omit minor details and repetitive examples. Use your own words to restate the key points concisely and objectively, without adding personal opinions or interpretations. Finally, organize the summary in a logical manner, maintaining the flow and connections between the main ideas.

To write an effective summary, one must identify the main topic and key supporting points of a text. Minor details and repetitive examples should be omitted, and the key points should be restated concisely and objectively using one's own words. The summary should be organized logically, maintaining the flow between main ideas.
