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 are the key points of this news item?  Summarize in two sentences.

Russia’s military acknowledged that a bomb accidentally dropped by one of its warplanes caused a powerful blast in a Russian city not far from Ukraine’s border, injuring two and scaring local residents.

Belgorod, a city of 340,000 located about 40 kilometers (25 miles) east of the Russia-Ukraine border, has faced regular drone attacks during Russia’s current military operation in Ukraine. Russian authorities blamed the earlier strikes on the Ukrainian military, which refrained from directly claiming responsibility for the attacks.

The explosion late Thursday was far more powerful than anything Belgorod residents had experienced before. Witnesses reported a low hissing sound followed by a blast that made nearby apartment buildings tremble and shattered their windows.
Response: Russia's military admitted that it had accidentally dropped a bomb in a Russian city, Belgorod, near the Ukrainian border. Belgorod had already encountered previous drone attacks, but this one frightened local residents.

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.

Outline the causes of the American Civil War in three sentences.

The American Civil War was primarily caused by deep-seated differences over slavery and states' rights. The Southern states wanted to maintain slavery as part of their economy, while the Northern states opposed its expansion into new territories. Political tensions and conflicts over these issues ultimately led to Southern secession and war.
