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: Explain to me what the main subject of this article is:

"California officials are investigating the disappearance of 30 tons (61,000 pounds) of ammonium nitrate from a railcar crossing the Midwest. Ammonium nitrate, which is used as fertilizer, can also be used to create explosives and was a key component in the homemade bomb used in the 1995 attack on the Murrah Federal Building in Oklahoma City. The chemical was shipped by train from Cheyenne, Wyoming last month but when it arrived in the Mojave Desert two weeks later, its holding car was empty and the nitrate was gone. Dyno Nobel, the company responsible for shipping the ammonium nitrate is a leader in commercial explosives and filed a report with the federal National Response Center (NRC) on May 10 and an investigation is currently underway.

The Federal Railroad Administration, the California Public Utilities Commission, Union Pacific, and Dyno Nobel are looking into the disappearance, and the railcar is being transported back to Wyoming to undergo a thorough inspection. It is unclear how or when the chemical disappeared during transit, but Dyno Nobel told KQED News, “The railcar was sealed when it left the Cheyenne facility, and the seals were still intact when it arrived in Saltdale. The initial assessment is that a leak through the bottom gate on the railcar may have developed in transit.”
Response: This article covers an ongoing investigation into the disappearance of 30 tons of ammonium nitrate that was being transported from Wyoming to the Mojave Desert by railcar. While mainly used as a fertilizer this substance can also be used as an explosive which raises security concerns.  Several agencies, including the California Public Utilities Commission, are investigating.

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.

In the context of students learning effective research and study skills, summarize the techniques and rationale for summarizing lengthy source materials concisely:

For students conducting academic research or reviewing dense materials for courses, possessing the skill of summarizing source materials concisely is invaluable. Learning to condense extensive information into succinct yet comprehensive summaries has myriad benefits. First, it enhances comprehension by forcing readers to identify core concepts and distinguish major points from unnecessary details. Close analysis and extraction of key ideas facilitates deeper understanding of complex content.  

Composing clear, objective summaries also develops critical thinking abilities through evaluation of significance, relevance, and logic of claims across multiple sources. It fosters concise expression by reframing ideas using disciplined, precise word choice rather than simply copying. Summaries capture the full essence using a fraction of the original length - invaluable for reviewing expansive materials efficiently.  

To summarize dense sources methodically: scan initially for the central thesis or focus, pinpoint topic sentences and supporting evidence, take notes on crucial details, rephrase using succinct language, organize points coherently, maintain informational objectivity, include citations, and check accuracy against the original. Practicing this process strengthens vital skills transferable across academic disciplines and professional contexts.

Summarizing source materials concisely enhances comprehension by forcing identification of core concepts and major/minor points. Composing summaries develops critical thinking through evaluating significance/logic of claims across sources. Precise wording captures the essence concisely rather than copying, improving expression. Summaries enable reviewing expansive materials efficiently. To summarize methodically: determine focus, note key details, rephrase succinctly, organize coherently, maintain objectivity, cite sources, check accuracy. Practicing builds comprehension, critical reasoning, concise communication - transferable skills crucial for academic/professional success.
