Extractive summarization techniques create summaries by selecting and concatenating the most important sentences or phrases from the original text. Their advantages include preserving the original text's integrity, being more straightforward to implement, and generally producing grammatically correct summaries. However, they may lack coherence and fail to capture the overall meaning or generate new sentences. Abstractive techniques, on the other hand, generate entirely new sentences that capture the key concepts, potentially producing more concise and coherent summaries. However, they are more complex, prone to errors, and may distort the original meaning. Extractive methods are suitable for applications like news article summarization, where preserving factual accuracy is crucial. Abstractive techniques may be better for summarizing longer documents, generating headlines, or producing creative summaries for scenarios like storytelling or advertising.

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: Hi. Please summarize the benefits of a Roth IRA in one sentence.

This is the paragraph I'd like you to summarize.

What Are the Advantages of a Roth IRA?
While Roth IRAs do not include an employer match, they do allow for a greater diversity of investment options. For individuals who anticipate that they will be in a higher tax bracket when they’re older, Roth IRAs can also provide a beneficial option. In Roth IRAs, you can withdraw your contributions (but not earnings) tax- and penalty-free.
Ultimately, you can manage how you want to invest your Roth IRA by setting up an account with a brokerage, bank, or qualified financial institution.

Response: With a Roth IRA, contributors can invest in more types of investment vehicles than traditional IRAs and because the contribution taxes are paid upfront, the beneficiary can withdraw the funds without taxes or penalties.

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.
