The two correct answers that support the inference that people have been more concerned with the health of honeybees than wild bumblebees in recent years are:
- The causes of bumblebee die-offs have been largely understudied.
- People are more familiar with honeybee die-offs.
These statements suggest a lack of attention and research on bumblebees compared to honeybees, indicating that there has been greater concern for honeybee health.
