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 indicate a greater public awareness and focus on honeybee health compared to the lack of attention given to the issues facing wild bumblebees.
