GLADSTONE INSTITUTE OF VIROLOGY AND IMMUNOLOGY
1991
Gladstone launches the Gladstone Institute of Virology and Immunology (GIVI) to address the rising HIV/AIDS crisis. Over the following years, GIVI helps define the life cycle of HIV, paving the way for many medications currently in use, and leads the groundbreaking iPrEx study, showing how a daily pill can prevent HIV infection in people likely to come in contact with the virus.
Response: In 1991, Gladstone Institute of Virology and Immunology is founded. It defines the life cycle of HIV and leads the iPrEx study, showing that a daily pill can prevent HIV.

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.
