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 main points covered in the following text about the evaluation of text summarization systems:

Evaluating the performance of text summarization systems is a critical but challenging task. There are several evaluation metrics and methods used to assess the quality of summaries generated by these systems. One common approach is to use intrinsic evaluation methods, which involve comparing the system-generated summaries against human-written reference summaries. Metrics like ROUGE (Recall-Oriented Understudy for Gisting Evaluation) measure the overlap between the system summary and the reference summaries in terms of n-gram co-occurrence. However, intrinsic evaluation methods have limitations, as they do not directly measure the usefulness or informativeness of the summaries for specific tasks or applications. To address this, extrinsic evaluation methods are used, which involve measuring the performance of the summarization system in the context of a specific task or application, such as information retrieval, question answering, or reading comprehension. Additionally, human evaluation is often considered the gold standard for assessing summary quality, as it involves subjective judgments from human annotators on aspects like coherence, informativeness, and overall quality. However, human evaluation can be time-consuming and expensive, and subject to variability and biases. Consequently, a combination of automatic and human evaluation methods is often used to provide a comprehensive assessment of summarization system performance.
