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: Summarize the main points in the text below - 

You'll always want to have access to sufficient emergency funds for, well, emergencies. Make sure you can afford a health emergency (some insurance plans require you to pay first and claim for reimbursement later), a one-way ticket home in the event that something urgent happens, a missed flight, or a theft or unexpected mishap. And, more practically, you may find that you've under-budgeted and you need to increase your budget a bit while you're on the road, so having access to some emergency cash might prevent you from having to cut your trip short or miss out on things you wanted to see.

In short, you need to be able to afford to get yourself out of bad situations if you really have to. Remember that as a solo traveler you will generally not have another person readily available to help with bad situations, so it's up to you to be able to manage them.

It's a good idea to have a variety of different sources of emergency funds, including cash in hard currencies like US dollars or Euros, a credit card (and backup) with a decent limit, and a trusted friend or relative back home who can send you money in an emergency.
Response: - Have money set aside for emergencies like health issues or an emergency trip home
- Budget enough to get yourself out of unexpected situations if needed
- Remember, if you’re by yourself you will be the one managing any problems
- Carry a few different ways to pay for things if needed like cash and credit cards, and  have someone to borrow from back home if needed

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 following text about summarization techniques:

Text summarization is the process of creating a concise and precise summary of a longer piece of text. The goal is to capture the most important information from the source while filtering out unnecessary details. 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 summary. This method preserves the original wording and phrasing. Algorithms often assign scores to sentences based on features like word frequency, position, and more. The highest-scoring sentences are then selected for the summary.

Abstractive summarization, on the other hand, aims to generate entirely new sentences that capture the key points of the source text. This approach involves understanding the semantic meaning of the text and paraphrasing it into a concise form. Techniques like information extraction, sentence fusion, and language generation are used. Abstractive summarization is more challenging but can produce more coherent and readable summaries.

In practice, hybrid approaches combining extractive and abstractive methods are common. The choice depends on factors like the domain, desired summary characteristics, and available resources. Evaluation of summaries considers criteria like informativeness, coherence, and faithfulness to the original content.
