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: Hello. Please examine the information below and summarize the goals set forth by President John F. Kennedy.

We set sail on this new sea because there is new knowledge to be gained, and new rights to be won, and they must be won and used for the progress of all people. For space science, like nuclear science and all technology, has no conscience of its own. Whether it will become a force for good or ill depends on man, and only if the United States occupies a position of pre-eminence can we help decide whether this new ocean will be a sea of peace or a new terrifying theater of war. I do not say the we should or will go unprotected against the hostile misuse of space any more than we go unprotected against the hostile use of land or sea, but I do say that space can be explored and mastered without feeding the fires of war, without repeating the mistakes that man has made in extending his writ around this globe of ours. 

There is no strife, no prejudice, no national conflict in outer space as yet. Its hazards are hostile to us all. Its conquest deserves the best of all mankind, and its opportunity for peaceful cooperation may never come again. But why, some say, the moon? Why choose this as our goal? And they may well ask why climb the highest mountain? Why, 35 years ago, fly the Atlantic? Why does Rice play Texas? 

We choose to go to the moon. We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too. 
Response: President John F. Kennedy shared several goals about the space race with the audience. He spoke of the goals of exploring space without going to war with other nations and not repeating the past mistakes made on Earth. The President asked the rhetorical question of why mankind should go to the moon. He answers that the goal of reaching the moon fulfills the challenge of overcoming the hardships and difficulties associated with that task.

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.

Identify the main points and key details from the following text about the history of the printing press:

The printing press is a device that allows for the mass production of uniform printed matter. It was one of the most influential inventions in human history, drastically changing the way information and knowledge were spread. The printing press was invented in 1440 by Johannes Gutenberg, a German goldsmith who adapted existing technologies like the screw press and movable type to create his revolutionary machine. This allowed books and other texts to be quickly and economically printed on a large scale for the first time.

Prior to Gutenberg's printing press, all books had to be copied by hand, a laborious and error-prone process. The first book printed with movable type was the Gutenberg Bible, also known as the 42-line Bible. Gutenberg's invention gave a major boost to the Renaissance by making knowledge more freely available across Europe and beyond. It radically changed society by spreading literacy and education farther than ever before possible.

Despite its impact, the printing press wasn't an overnight success due to stringent censorship and the stratospheric cost of manufacturing books at first. It took many decades before printed works became widely affordable and available. However, the printing press ultimately led to revolutions in literature, science, religion, and education by enabling the spread of new ideas on an unprecedented scale. It democratized access to information and empowered a new era of free thought.
