The official synopsis for "Guardians of the Galaxy Vol. 3" from Marvel Studios reads:


"Peter Quill, still reeling from the loss of Gamora, must rally his team around him to defend the universe along with protecting one of their own. A mission that, if not completed successfully, could quite possibly lead to the end of the Guardians as we know them."

As evidenced from the film's trailers, it seems as though the Guardians will be protecting Rocket from the High Evolutionary, as the two of them apparently have an intense backstory.

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.

Condense the basic principles of supply and demand into two sentences: Supply and demand is an economic model of price determination in a market. It postulates that, holding all else equal, in a competitive market, the unit price for a particular good will adjust to equilibrate the quantity demanded by consumers and the quantity supplied by producers, resulting in an economic equilibrium of price and quantity. The quantity of a good supplied (i.e., the amount that owners or producers offer for sale) rises as the market price rises, and falls as the price falls, while the quantity of a good demanded falls as the price rises, and rises as the price falls.

The principles of supply and demand state that the price of a good in a competitive market adjusts to equate the quantity demanded by consumers with the quantity supplied by producers, achieving economic equilibrium. Supply increases with rising prices and decreases with falling prices, while demand decreases with rising prices and increases with falling prices.
