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: What does this paragraph say about clashes between the higher and lower classes?

During the Renaissance, chokers made a comeback as a stylistic choice for higher-class citizens and, later, they were popular during the 1700s in Europe. As time went on, the manner in which one wore a choker could mean multiple things. Commoners wore red ribbons for countrymen who were victims of the guillotine and, by the 1800s, a single black ribbon around the neck meant prostitution. Thus, a strange clash between higher class and conventionally “virtuous” women and lower-class women emerged as the accessory evolved.
Response: During the Renaissance and in 18th century Europe, chokers were a favorite of the upper classes. When commoners started wearing similar accessories for political reasons and to denote sex work, this led to class conflict.

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 about the evaluation of summarization systems from the following passage:

Evaluating the quality of summarization systems is a challenging task due to the subjective nature of what constitutes a good summary. Human evaluation is often considered the gold standard, where human annotators assess the summaries based on criteria such as informativeness, coherence, and linguistic quality. However, this process is time-consuming and expensive, especially for large-scale evaluations. As a result, various automatic evaluation metrics have been developed, including ROUGE (Recall-Oriented Understudy for Gisting Evaluation), which measures the overlap between the system-generated summary and human-written reference summaries. While automatic metrics are efficient and consistent, they may not fully capture the nuances of human evaluation. Recent efforts have focused on developing more sophisticated evaluation methods that combine automatic metrics with human judgments, as well as task-based evaluations that assess the utility of summaries for specific applications.

The passage discusses the challenges of evaluating summarization systems, highlighting the trade-off between human evaluation, which is subjective but considered the gold standard, and automatic metrics like ROUGE, which measure overlap with reference summaries efficiently but may not capture all nuances. Recent efforts aim to combine automatic and human evaluations, as well as task-based assessments to measure the utility of summaries for specific applications.
