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 use of color in decorating. Here is the link:
Color
Choosing a color palette is an essential part of interior design. While you could have a different style and color scheme in each room, often you will want to tie the whole dwelling together. Consider the right colors for a small room as well as colors and patterns for a large room.
Response: In interior design, not only do you want to choose the right colors for individual rooms, you want to use colors that tie the whole dwelling together.

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 evaluation metrics and challenges in assessing the quality of text summaries. Here is the long text: Evaluating the quality of text summaries is a crucial aspect of developing and improving summarization systems. Several evaluation metrics have been proposed, each with its own strengths and limitations. Recall-based metrics, such as ROUGE (Recall-Oriented Understudy for Gisting Evaluation), measure the overlap between the generated summary and reference summaries. While widely used, these metrics focus solely on content selection and may not capture other important aspects like coherence and fluency. Other metrics, like pyramid scoring, aim to assess the quality of the summary content itself, but require manual effort in creating reference summaries. More recently, researchers have explored using human evaluations and task-based metrics to better capture the usefulness and readability of summaries. However, achieving reliable and consistent human evaluations can be challenging and time-consuming. Additionally, evaluating summaries for specific domains or genres poses unique challenges due to domain-specific terminology and conventions.
