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: Can you sum up what these former survivor players said about meeting Jeff Probst in a few sentences?

"Survivor: Island of the Idols" player Elaine Stott said that although she was nervous before she met the "Survivor" host, the fact that she was sitting in front of producers and Probst "didn't really matter to me." 

"I told dirty jokes, I flirted, I cussed, I made fun of myself. That's just how I am in general," Stott told Insider. "... I said, 'Jeff, you're just a man, you put your britches on just like I do.'" 

Freberg added that the interviewers just "tell you to start talking" instead of asking direct questions, and Probst sits there "trying to size you up and trying to be intimidating."

"You just need something funny to say, so I made it up on the spot," Freberg recalled. "... I look at Jeff and I go, 'My grandma's gonna freak the f--- out when she finds out I met you.'"

Freberg added that his joke "got a big laugh," so he was "off to a good start after that."
Response: When Elaine Stott was in front of Probst and producers her nervousness went away. Freberg said the producers didn't ask questions and he was told to just start talking. Jeff sized them up, but Freeberg came up with a funny joke from the start and that put them on good terms for the rest of the interview.

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.

Would you be able to summarize this information about the history of electric cars? "Electric cars are not a recent invention; they date back to the early 19th century. Robert Anderson built the first crude electric carriage around 1832. In the 1870s, notable improvements were made by innovators like Thomas Parker. By the early 20th century, electric cars were fairly common and even outnumbered gasoline cars in some places due to their ease of operation and lower noise. However, the mass production of gasoline cars by manufacturers like Ford significantly lowered gas car prices, leading to a decline in the use of electric cars. It wasn't until late in the 20th century, amid concerns about pollution and energy sustainability, that electric cars regained attention, paving the way for modern electric vehicles with advanced technologies."

Electric cars have been around since the early 19th century, with Robert Anderson's crude electric carriage in 1832 and improvements in the 1870s. They were common by the early 20th century but declined due to the mass production of cheaper gasoline cars. Interest in electric cars revived in the late 20th century because of pollution and sustainability concerns, leading to modern advancements.
