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: Using this text, summarize how guessing the wrong word helped the writer solve the puzzle.

RATES

None of the letters were correct, so I now wanted to find a word that used the two next most common vowels, I and O, together with some other common consonants:

DOING

The word was now taking shape: I had three of the letters, two in the correct position. It looked as though the D must come at the end of the word, and there was a good chance that the letter between O and N would be a U:

POUND

My third guess confirmed my ideas about the general shape of the word. Now all I had to do was find the first letter. My problem was that I could think of five possible answers that all fitted the pattern using letters that were still available: BOUND, FOUND, HOUND, MOUND, WOUND. But I had only three guesses remaining, so if the answer was my fourth or fifth guess, I would lose the game. My chances were only 60%. Could I do anything to improve the odds? Yes! If I could come up with a word that contained three of the candidate letters B, F, H, M and W, I could either confirm or eliminate those letters in a single guess and so ensure that I won the game, even if I forfeited the chance of winning immediately:

WOMBS

I did not find the missing letter, but at least this guess served its purpose of eliminating three of the possible solutions, WOUND, MOUND, AND BOUND. So the answer had to be either FOUND or HOUND, and I still had two guesses left. I managed to pick the correct one:

FOUND

As with Wordle #281, using up one of my guesses on a word that I knew was not the correct solution proved to be a good way to win the game. In fact, if I had gone with the alternative of WHIFF instead of WOMBS for my fourth guess, I would have found out that the solution contained an F and my fifth guess would have been a certainty rather than a fifty-fifty chance.
Response: The writer chose a word they new was incorrect in order to eliminate potential letters faster than guessing the correct letters with single-letter modifications.

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.

Based on the text, outline the effect of the Industrial Revolution on urbanization.
