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: Summarize this paragraph in a few sentences:
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.

Summarize this article about the effects of climate change on polar bears:
    The article discusses how the increasing temperatures and melting ice in the Arctic region are impacting polar bear populations. It mentions that as the sea ice diminishes, polar bears are finding it increasingly difficult to hunt seals, their primary prey. Consequently, the bears have to travel greater distances and expend more energy, leading to a decline in their body condition and reproductive rates. The article also highlights conservation efforts being made to protect polar bear habitats and mitigate the effects of global warming.

Climate change is causing the Arctic sea ice to melt, making it harder for polar bears to hunt seals. This leads to poorer body condition and lower reproductive rates. Conservation efforts are underway to protect their habitats and combat global warming.
