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 principles for effective summarization:

Effective summarization requires a thorough understanding of the source material, the ability to discern the essential information from the non-essential, and the skill to communicate the key points clearly and concisely. The summary should capture the main ideas and key supporting details while omitting unnecessary or redundant information. It should be written in a neutral and objective tone, without introducing personal biases or interpretations. The language used should be clear and concise, avoiding excessive wordiness or verbatim copying from the original text. The summary should be organized in a logical and coherent manner, preserving the flow and structure of the original content. Additionally, it is important to maintain accuracy and fidelity to the source material, ensuring that the summary does not misrepresent or distort the original meaning.
