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: Provide a brief summary of the first few paragraphs from this article on drunk driving.

WASHINGTON, D.C. — Drunk driving claimed the lives of 10,511 people in 2018, a 3.6% decrease after two straight years of nearly 11,000 alcohol-related traffic deaths, according to new data released today by the National Highway Traffic Safety Administration (NHTSA). Drunk driving remains the leading killer on America’s roads, accounting for 29% of all traffic deaths. (NHTSA FARS 2018 by state)

“We are starting to see some improvements, but it is appalling that we are still losing over 10,000 lives to this violent, preventable crime,” said MADD National President Helen Witty. “The overall number of traffic deaths and those caused by drunk driving have remained stubbornly higher than in 2014, the last year when drunk driving deaths dropped below 10,000. That’s unacceptable. And it’s why we are calling for Congress to pass legislation that would mandate advanced drunk driving prevention technology in all new vehicles. It’s past time to make this a standard safety feature and start saving lives.”

Technology is a major component of MADD’s Campaign to Eliminate Drunk Driving, launched in 2006. The Campaign supports development of advanced drunk driving prevention technology, high-visibility law enforcement, such as sobriety checkpoints and saturation patrols, state laws requiring ignition interlocks for all drunk driving offenders, and public support for these initiatives. Drunk driving deaths have decreased by 22 percent since the Campaign launched, but the past four years underscores that more must be done
Response: Despite a 3.6% decrease in drunk driving deaths, it still remains the leading cause of traffic-related deaths. Many are calling for Congress to pass legislation that would implement drunk driving prevention technology in new vehicles. Drunk driving deaths have decreased by 22% since the start of the Mothers Against Drunk Driving campaign, but there is still much work to be done.

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 concept of 'supply and demand' in economics.

The concept of 'supply and demand' in economics describes how the availability of a product (supply) and the desire for that product (demand) affect its price. When demand exceeds supply, prices tend to rise. Conversely, if supply exceeds demand, prices usually fall. This principle helps determine the market equilibrium price.
