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.

Summarize the following scientific discovery in a few sentences.
                    The discovery of penicillin by Alexander Fleming in 1928 revolutionized modern medicine. While working at St. Mary's Hospital in London, Fleming noticed that a mold called Penicillium notatum had killed bacteria on a petri dish. This observation led to the development of the first antibiotic, penicillin, which could effectively treat a wide range of bacterial infections. Penicillin's discovery has saved countless lives and laid the groundwork for the development of other antibiotics, fundamentally changing the treatment of bacterial diseases.
