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: In one sentence, summarize what brought the Spanish Habsburg's reign to an end.

The researchers, led by geneticist Román Vilas from Spain’s University of Santiago de Compostela, focused on 15 members of the so-called Spanish Habsburgs. While the Habsburg family rose to power in central Europe as the rulers of Austria, Germany and eventually the Holy Roman Empire, the family’s influence spread westward to Spain after Philip I, son of the second Habsburg Holy Roman Emperor, married Joan of Castile in 1496. The Spanish Habsburgs’ reign lasted two centuries, until the 38-year-old Charles II, a king whose manifold health woes and infertility scholars often attribute to severe inbreeding, died in 1700 with no immediate heir.
Response: The Spanish Habsburg's last king, Charles II, died without an heir because of his many health problems and infertility due to severe inbreeding.

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.
