Summarize the key information in this article about the history of the printing press:

The printing press was invented in the Holy Roman Empire by the German Johannes Gutenberg around 1440, based on existing screw presses. Gutenberg, a goldsmith by profession, developed a printing system by adapting existing technologies to printing purposes, as well as making skillful use of the metadata of each trade to circumvent some of the limitations of current period print methods. His newly devised hand mould made possible the precise and rapid creation of metal movable type. His typeface was modelled on existing German handwriting of the time combined with traditions of printing from much earlier periods and countries. The appearance of Gutenberg's Bible in the mid-1450s is considered the effective start of the 'Gutenberg Revolution' and the age of the printed book in the West.

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 summarize this in one or two sentences:

The V. C. Morris Gift Shop is located at 140 Maiden Lane in downtown San Francisco, California, United States, and was designed by Frank Lloyd Wright in 1948. The store was used by Wright as a physical prototype or proof of concept for the circular ramp at the Solomon R. Guggenheim Museum.[1]

All of the built-in furniture is constructed out of black walnut, is original to the renovation, and was designed by Manuel Sandoval, who apprenticed and worked with Frank Lloyd Wright.[2][3]

Response: Frank Lloyd Wright's V.C. Morris Gift Shop in downtown San Francisco was designed in 1948 and was a prototype for the circular ramp at the Guggenheim Museum. The black walnut built-in furniture was designed by Manuel Sandoval.

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.
