Summarize the following paragraph about abstractive and extractive summarization: There are two main types of summarization: abstractive and extractive. Abstractive summarization attempts to produce a concise version of the original text by rephrasing the most important ideas using new words and sentence structures. This approach requires understanding the semantic meaning of the text and generating an entirely new summary. In contrast, extractive summarization selects and concatenates the most salient sentences from the original text, preserving the exact words and phrasing used by the author. Extractive methods are generally faster and simpler to implement, while abstractive summarization can produce more natural and coherent summaries at the expense of increased complexity.

The paragraph outlines two summarization approaches: abstractive and extractive. Abstractive summarization rephrases the main ideas using new words and sentences, requiring semantic understanding and text generation. Extractive summarization selects and combines the most important sentences verbatim from the original text. Extractive methods are simpler but produce less natural summaries, while abstractive summarization is more complex but can generate more coherent summaries.

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.
