Explanation:

1. The main topic of the first - part questions is about polar bear habitats and specialization. Polar bear habitats are threatened mainly due to climate change which is often related to human - induced factors such as greenhouse gas emissions. Specialization can be a double - edged sword for polar bears.
2. For the second question, specialization in polar bears means they are well - adapted to their arctic environment. Their physical and behavioral traits are optimized for hunting in the arctic.

Answer:

1. Multiple factors contribute to the threat of polar bear habitats. Climate change (linked to human activities) is a major cause. But among the given options, the most relevant one for the overall context seems to be how polar bear habitats became threatened.
2. C. Polar bears hunt well in arctic areas. Their specialization is in adapting to the arctic environment for hunting.
