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: Please summarize how Asian American and Pacific Islander Heritage Month was started based on the text below: 

History
A former congressional staffer in the 1970s, Jeanie Jew, first approached Representative Frank Horton with the idea of designating a month to recognize Asian Pacific Americans, following the bicentennial celebrations.[19] In June 1977, Representatives Horton, and Norman Y. Mineta, introduced a United States House of Representatives resolution to proclaim the first ten days of May as Asian-Pacific Heritage Week.[20][21] A similar bill was introduced in the Senate a month later by Daniel Inouye and Spark Matsunaga.[20][22]

The proposed resolutions sought that May be designated for two reasons. For on May 7, 1843, the first Japanese immigrant arrived in the United States.[23][24][25] More than two decades later, on May 10, 1869, the golden spike was driven into the first transcontinental railroad, which was completed using Chinese labor.[23][24][26]

President Jimmy Carter signed a joint resolution for the celebration on October 5, 1978.[20]

On May 1, 2009, President Barack Obama signed Proclamation 8369, recognizing the month of May as Asian American and Pacific Islander Heritage Month.[1][27]
Response: A former congressional staffer with the idea approached a representative about it in the 1970s. In 1977, a resolution was introduced in the House and the Senate, and the President signed it in 1978. However, that resolution was only for the first ten days of May. It wasn't until 2009 that the whole month of May was named Asian American and Pacific Islander Heritage Month.

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 discussed about the evaluation of summarization systems in the following text:

Evaluating the performance of summarization systems is crucial for understanding their capabilities and limitations, driving research progress, and ensuring they meet the desired requirements for real-world applications. However, evaluation is a challenging task due to the inherent subjectivity and complexity involved in assessing the quality and usefulness of summaries.

Evaluations can be broadly classified into two categories: intrinsic and extrinsic. Intrinsic evaluations focus on analyzing the summary itself, assessing aspects like informativeness, coherence, and linguistic quality. Common intrinsic metrics include ROUGE, which measures overlap between the system summary and human-written reference summaries, and newer metrics like BERTScore that consider semantic similarity.

Extrinsic evaluations, on the other hand, measure the performance of the summary in a downstream task or application, such as information retrieval, question answering, or decision-making. These evaluations aim to capture the summary's practical utility and evaluate its ability to support human users in completing specific tasks effectively.

Both intrinsic and extrinsic evaluations have their advantages and limitations. Intrinsic metrics provide a standardized way to compare different systems but may not fully capture the summary's usefulness, while extrinsic evaluations are more application-oriented but can be costly and time-consuming to conduct. Recent research has also explored human evaluation, where human assessors rate the quality of summaries based on various criteria, as well as novel evaluation methods that combine multiple perspectives.

Evaluating summarization systems is crucial but challenging due to the subjectivity involved. Intrinsic evaluations assess the summary itself through metrics like ROUGE and BERTScore, measuring aspects like informativeness and coherence. Extrinsic evaluations measure performance in downstream tasks like information retrieval, capturing practical utility. Human evaluation and novel combined methods are also being explored. Both intrinsic and extrinsic evaluations have pros and cons, with intrinsic metrics providing standardized comparison but potentially missing usefulness, while extrinsic evaluations are application-oriented but costlier.
