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 challenges of automatic text summarization:

Automatic text summarization is a complex task that poses several challenges. One major challenge is dealing with ambiguity and context in natural language. Words and phrases can have multiple meanings, and their interpretations often depend on the surrounding context. Summarization systems must be able to accurately interpret the semantics of the text to identify the most salient information. Another challenge is ensuring the coherence and readability of the summary. Simply extracting and combining key sentences from the original text can result in a disjointed and incoherent summary. Effective summarization requires understanding the logical flow and relationships between different parts of the text to produce a cohesive and coherent summary. Additionally, handling different text genres and domains can be problematic, as the language, style, and structure can vary significantly across different types of documents. Summarization systems must be adaptable and robust to handle diverse inputs. Furthermore, evaluating the quality of summaries is a non-trivial task, as it involves subjective judgments and can be influenced by various factors such as the intended use case, the target audience, and the specific requirements of the summarization task.
