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: In two sentences, tell me the main points from the news article.

The article in reference:
Eighteen-hundred people were called as potential jurors, and the pool whittled down to 10 men and eight women last week.
All 16 will hear the case, but only 12 will actually take part in deliberations to decide Vallow Daybell’s guilt or innocence. The other six are alternates and will be released from service before deliberations begin. Jurors will not be notified they are an alternate until it is time for deliberations in order to ensure they all stay engaged throughout the trial.
The trial is expected to take up to 10 weeks.
Chad Daybell, seen during a 2020 court appearance, has also pleaded not guilty. Only Vallow Daybell’s trial begins Monday.

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.

Provide a concise summary of the main points presented in the following passage about the history of the printing press: Johannes Gutenberg's invention of the movable-type printing press in the 15th century revolutionized the spread of information and ideas. Before this innovation, books had to be laboriously copied by hand, making them rare and accessible only to the wealthy. Gutenberg's press allowed for the mass production of printed materials, drastically reducing the cost and time required for book production. This technological breakthrough paved the way for the Renaissance, the Protestant Reformation, and the Scientific Revolution by enabling the rapid dissemination of knowledge across Europe.
