Explain the difference between extractive and abstractive summarization methods, based on the following text: There are two main approaches to summarization: extractive and abstractive. Extractive summarization involves selecting and concatenating the most important sentences or phrases from the original text to form the summary. This method retains the exact wording and phrasing of the source material, making it simpler to implement but potentially lacking in coherence or fluency. On the other hand, abstractive summarization generates a new, concise representation of the text by rephrasing and reorganizing the information in a way that is more human-like and coherent. This approach involves understanding the semantic meaning of the text and generating new sentences that capture the essence of the content. While more challenging to develop, abstractive summaries can be more readable and tailored to the target audience.

The key difference between extractive and abstractive summarization methods is that extractive summarization selects and concatenates important sentences or phrases from the original text to form the summary, retaining the exact wording, while abstractive summarization generates a new, concise representation of the text by rephrasing and reorganizing the information in a more coherent and human-like way. Extractive methods are simpler to implement but may lack fluency, while abstractive methods involve understanding the semantic meaning and generating new sentences, resulting in more readable and tailored summaries, though more challenging to develop.

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: Please summarize the goals for scientists in this text:

Within three days, the intertwined cup nest of grasses was complete, featuring a canopy of overhanging grasses to conceal it. And decades later, it served as Rinkert’s portal to the past inside the California Academy of Sciences. Information gleaned from such nests, woven long ago from species in plant communities called transitional habitat, could help restore the shoreline in the future. Transitional habitat has nearly disappeared from the San Francisco Bay, and scientists need a clearer picture of its original species composition—which was never properly documented. With that insight, conservation research groups like the San Francisco Bay Bird Observatory can help guide best practices when restoring the native habitat that has long served as critical refuge for imperiled birds and animals as adjacent marshes flood more with rising sea levels. “We can’t ask restoration ecologists to plant nonnative species or to just take their best guess and throw things out there,” says Rinkert.
Response: Scientists are studying nests hoping to learn about transitional habitats that could help restore the shoreline of San Francisco Bay.

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.
