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: Summarize this paragraph in a few sentences:
GLADSTONE INSTITUTE OF VIROLOGY AND IMMUNOLOGY
1991
Gladstone launches the Gladstone Institute of Virology and Immunology (GIVI) to address the rising HIV/AIDS crisis. Over the following years, GIVI helps define the life cycle of HIV, paving the way for many medications currently in use, and leads the groundbreaking iPrEx study, showing how a daily pill can prevent HIV infection in people likely to come in contact with the virus.
Response: In 1991, Gladstone Institute of Virology and Immunology is founded. It defines the life cycle of HIV and leads the iPrEx study, showing that a daily pill can prevent HIV.

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 brief summary of the following passage about the history of the printing press:

The printing press is a device that applies pressure to an inked surface resting upon a print medium, thereby transferring the ink. It marked a dramatic improvement over earlier printing methods, allowing for the mass production of printed books and making knowledge more widely available. The earliest known movable type system was created in China around 1040 AD by Bi Sheng, while the first known movable type printing technology in Europe was created by Johannes Gutenberg around 1440 AD. Gutenberg's invention of mechanical movable type printing started the Printing Revolution and is widely regarded as one of the most influential events in modern history.
