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 text say in one sentence?

Onceropyga pulchra is a species of moth in the family Zygaenidae. It is found in Australia in south-eastern Queensland and eastern New South Wales.[1]

The length of the forewings is 6.5 mm for males and 8 mm for females. The upperside of the forewings is dark brown with a slightly lighter spot at the end of the cell, distally bordered by a suffusion of blackish scales. The underside is dark grey brown, but slightly lighter medially. The hindwings are blackish on both sides, but slightly lighter basally, with a light brown costal margin.[1]
Response: Onceropyga pulchra, a species of moth found in south-eastern and eastern Australia, has wings between 6.5-8mm in length, is dark and lighter brown with blackish scales on the upperside and dark grey-brown and blackish coloring on the underside.

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 presented in the following passage about the challenges and limitations of summarization:

While summarization is a valuable skill, it is not without its challenges and limitations. One of the primary difficulties lies in determining what constitutes the most important or relevant information within a text. This can be subjective and influenced by factors such as the reader's prior knowledge, biases, and purpose for summarizing the material.

Another challenge is accurately capturing the nuances and connotations of the original content. Summarization often necessitates condensing complex ideas or arguments into simplified statements, which can potentially lead to oversimplification or loss of context. This is particularly problematic when summarizing analytical or interpretative works, where the author's intent, tone, and framing are crucial.

Additionally, summarization can be time-consuming and labor-intensive, especially when dealing with lengthy or highly technical materials. Achieving a concise yet comprehensive summary requires careful reading, analysis, and synthesis, which can be a demanding process, particularly for those lacking expertise in the subject matter.

Further, the efficacy of a summary depends on the skill and expertise of the summarizer. Inexperienced or untrained individuals may struggle to identify the most salient points, maintain objectivity, or convey the information accurately and coherently. Effective summarization often requires practice, feedback, and a deep understanding of the principles and techniques involved.

Summarization faces challenges like determining the most important/relevant information subjectively, accurately capturing nuances and connotations without oversimplification or loss of context, being time-consuming for lengthy/technical materials, and requiring skilled summarizers to identify key points objectively and convey information accurately. The efficacy of summaries depends on the expertise and training of the summarizer, as well as their understanding of summarization principles.
