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 what caused the writer's strike and how Netflix was involved according to this article.

Netflix’s one-two punch in cancellations underscored just how much the streaming giant has emerged as an avatar for the writers’ complaints. The writers, who are represented by affiliated branches of the Writers Guild of America, have said that the streaming era has eroded their working conditions and stagnated their wages despite the explosion of television production in recent years, for much of which Netflix has been responsible.

The W.G.A. had been negotiating with the Alliance of Motion Picture and Television Producers, which bargains on behalf of all the major Hollywood studios, including Netflix, before talks broke down last week. The writers went on strike on May 2. Negotiations have not resumed, and Hollywood is bracing for a prolonged work stoppage.

Last week, at a summit in Los Angeles a day after the strike was called, one attendee asked union leaders which studio has been the worst to writers. Ellen Stutzman, the chief negotiator of the W.G.A., and David Goodman, a chair of the writers’ negotiating committee, answered in unison: “Netflix.” The crowd of 1,800 writers laughed and then applauded, according to a person present at that evening who spoke on condition of anonymity because of the sensitivity of the strike.
Response: Television and film writers are striking due to their working conditions and wages. The WGA has stated that this is largely due to the rise of streaming services such as Netflix. The WGA, representing the writers, and the Alliance of Motion Picture and Television Producers, representing the studios, had previously been trying to negotiate a deal. They were unable to agree, and so the writers began striking on May 2nd. According to an anonymous source, Netflix was stated to be the worst studio to work for by the writer's union.

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 reasons behind the financial crisis of 2008 as laid out in this document.
user
The financial crisis of 2008 was primarily caused by the collapse of the housing bubble, risky lending practices, and the failure of financial institutions. High-risk mortgage loans and the bundling of these loans into securities led to widespread defaults and a liquidity crisis, eventually resulting in a global economic downturn.
