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.

Summarize the key points discussed in the following passage on the topic of summarization techniques:

Summarization is the process of condensing a text into a shorter form while preserving its essential information and overall meaning. There are two main approaches to summarization: extractive and abstractive. Extractive summarization involves identifying and extracting the most important sentences or phrases from the original text and combining them to form a concise summary. This approach relies heavily on scoring sentences based on features like word frequency, position in the text, and the presence of certain cue words or phrases. In contrast, abstractive summarization aims to produce a new, rewritten summary by understanding the semantic meaning of the text and generating novel sentences that capture the key points. This approach often utilizes advanced natural language processing techniques like semantic representation, sentence compression, and language generation models. While extractive methods are generally simpler and faster, abstractive summaries can be more coherent and concise. Many modern summarization systems combine both approaches to leverage their respective strengths.
