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: Could you summarize what this article says are ways to use essential oils? The article says:
AROMA DIFFUSER
This method is beneficial for mood enhancement and upliftment.  It disinfects the air and can boost immunity through inhalation.  Fill the bowl with water, add 5-15 drops and enjoy
STEAM INHALATION
This method is used mainly for upper respiratory problems such as bronchial and sinus congestion, colds, coughs, and influenza.  Fill a large bowl with boiling water and add three drops of essential oil.  Lean over the bowl with your eyes closed and a towel over your head and inhale the steam for 5-10 minutes.
VAPORIZER
An effective decongesting method for respiratory conditions.  Add from 3 to 9 drops of essential oil to the water of the vaporizer.  Run overnight.
Response: Three ways to use essential oils include in an aroma diffuser, via steam inhalation, and in a vaporizer. 

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.

Provide a concise summary of the following passage:

Text summarization is the process of creating a shortened version of a text document that captures the essential information and core meaning. The main goals are to reduce the length and remove redundant or irrelevant details while preserving the key points and overall meaning. This is useful for quickly understanding long documents, reports, or articles without having to read the entire text. Summarization techniques analyze the text and identify the most important sentences or sections to include in the summary based on factors like word frequency, sentence position, and cue phrases. Both extractive and abstractive methods can be used, with extractive summarization simply extracting the most relevant sentences and abstractive summarization paraphrasing and generating new sentences to create a more coherent summary.

Text summarization condenses a lengthy text into a concise version that retains the core information and meaning. It analyzes the text to identify key sentences or sections and either extracts them directly (extractive) or paraphrases them into new sentences (abstractive) to produce a shortened summary that conveys the essential points.
