Write a summary of the following paragraph about the process of text summarization:

Text summarization is the process of creating a concise and precise summary of a longer text document. It aims to capture the key points and overall meaning of the original text in a condensed form. Summarization can be extractive, selecting and concatenating the most salient sentences from the source, or abstractive, generating entirely new sentences that convey the essence of the text. Modern approaches often use deep learning models to analyze the semantics and context of the text. The quality of a summary is typically evaluated based on criteria like informativeness, coherence, and non-redundancy.

Text summarization involves creating a concise summary that captures the key points and meaning of a longer text document. It can use extractive methods by selecting important sentences, or abstractive methods by generating new sentences. Deep learning models analyze text semantics and context in modern approaches. Summaries are evaluated based on informativeness, coherence, and non-redundancy.

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.
