Explain the difference between extractive and abstractive summarization.
user
Extractive summarization involves selecting and combining the most important sentences or phrases from the original text to form the summary. In contrast, abstractive summarization aims to generate entirely new sentences that capture the essence of the original text, often rephrasing and restructuring the information. Abstractive methods require a deeper understanding of the text's meaning and may produce more concise and readable 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: Sum up the tips Joanna gives in the following article.

The article:
Give the shower curtain some texture

Joanna uses a ruffled white shower curtain for this bathroom, which she points out how this will make a statement in such a small space. However, choosing lighter colors still makes the space feel bigger.

Add extra lighting

One of the things that Joanna encourages people to do is make room in the budget for extra lighting. In the bathroom she designed, Joanna uses a vanity as well as an antique chandelier to give the space plenty of light. And what does light do? “Light makes things feel bigger so that’s the trick,” said Joanna. Learn what effortless tasks clutter-free people do every day.

Add a vanity mirror

Along with the ruffled shower curtain, Joanna says a vanity mirror can make a huge statement in such a small space. In the bathroom she worked on, she repainted an antique mirror she found, leaving some of the wood unpainted to give it the distressed look.

Since the countertop is smaller, Joanna decided to use a raised vessel sink to make the bathroom feel larger. She says this helps to give the sink and counter the illusion that it’s bigger than it actually is.
Response: Joanna suggests using a textured shower curtain to make a statement in a small space and that adding extra lighting because light makes rooms feel larger. Also adding a vanity mirror will make a statement in that small bathroom.

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.
