Answer:
Article A focuses on the importance of the sea otter grooming its fur, but Article B shows that the sea otter's grooming habits endanger it when the water is not clean.
Step-by-step explanation:
Adult sea otters spend more than a third of their day grooming their fur. This isn't for vanity; it's for survival.
When an otter's fur is covered in oil, it can no longer keep the otter warm. This can cause hypothermia and even death.
