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: What does this article say about Uber? Text below:

Two brothers who drive for Uber recently conducted an experiment. They opened their Uber apps while sitting in the same room, and tested which brother could earn more money to do the same work.

In a video published on The Rideshare Guy YouTube channel, the brothers recorded themselves looking for rides on the app. They found that Uber showed them nearly identical jobs, but offered to pay one of them a little better. The siblings could only guess why. Had Uber's algorithm somehow calculated their worth differently?

University of California College of the Law professor Veena Dubal says that's exactly what's going on. In a recent paper, she says rideshare apps promote "algorithmic wage discrimination" by personalizing wages for each driver based on data they gather from them. The algorithms are proprietary, so workers have no way of knowing how their data is being used, Dubal says.

"The app is their boss," Dubal told Morning Edition's A Martinez. "But unlike a human boss who you can negotiate with or withhold information from, the algorithms know so much about these workers."

Uber says workers who drive electric vehicles get a $1 bonus per ride, but the company does not use drivers' personal data to set their pay rates. "Uber does not personalize fares to individual drivers, and a driver's race, ethnicity, acceptance rate, total earnings, or prior trip history are not considered when calculating fares," a spokesperson writes in a statement. A representative for Lyft calls Dubal's paper "biased", saying it relies on cherry-picked data and debunked anecdotal information.

Personalized digitized pay is already the new normal in some workplaces, according to Dubal, and it's begun to attract attention from regulators. 
Response: This article states that Uber was paying one brother more to do the same job. It also says that a spokesperson for Uber doesn't personalize fares according to personal data, but that workers who drive electric vehicles get a bonus every ride.

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 following passage about the invention of the printing press and its impact on the spread of knowledge:

The printing press is widely regarded as one of the most important inventions in human history, dramatically transforming how information was shared and disseminated across the world. Before the printing press, books and documents were painstakingly handwritten, making them scarce and accessible only to wealthy individuals or institutions. This all changed in the 15th century when Johannes Gutenberg, a German goldsmith and inventor, introduced a revolutionary printing technique that used movable metal type and a screw-type press. Gutenberg's printing press mechanized the process of printing, allowing books to be mass-produced relatively quickly and inexpensively. As a result, knowledge and ideas could spread more rapidly and widely than ever before. The printing press played a pivotal role in the Renaissance by making classical texts from ancient Greece and Rome widely available, fueling a revival of learning and intellectual inquiry. It also facilitated the spread of religious texts like the Bible, contributing to the Protestant Reformation. Moreover, the printing press enabled the rise of modern journalism and the circulation of news, scientific discoveries, and political ideas, ultimately fostering social and political revolutions. In short, Gutenberg's printing press was a catalyst for the democratization of knowledge, empowering individuals with access to information and promoting the exchange of ideas on an unprecedented scale.
