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.

Give a concise summary of the following guidelines for summarizing a non-fiction text:

To summarize a non-fiction text effectively, begin by carefully reading through the entire text once to understand the main topic, purpose, and overall content. Take notes on the central argument or thesis, as well as major supporting points or key evidence. After grasping the material, read through again more critically, identifying the most essential information to include in the summary and separating it from secondary details or examples that can be omitted. When writing the summary, state the main thesis or focus of the text upfront in a clear topic sentence. Proceed to objectively explain the key supporting points or evidence, presenting information logically and concisely while avoiding subjective commentary or excessive details. Use your own wording while precisely capturing the original meaning. Omit digressions, redundancies, and overly specific examples. The summary should be significantly shorter than the original while preserving its core substance.

To effectively summarize a non-fiction text: Carefully read to grasp the central topic/argument and key points. Critically identify and note essential information to include vs. secondary details to omit. State the main thesis upfront. Objectively and concisely explain supporting points/evidence in a logical sequence using your own wording. Preserve the original meaning while omitting digressions, redundancies, examples. The summary should be substantially shorter while retaining the core substance.
