The two pieces of evidence from the text that best support the inference that people have been more concerned with the health of honeybees than wild bumblebees in recent years are:
- People are more familiar with honeybee die-offs.
- The causes of bumblebee die-offs have been largely understudied.
These statements imply a greater public awareness and concern for honeybees compared to bumblebees, as well as a lack of research focus on bumblebee health issues.
