The best evidence from the text that supports the inference that advice to people who want to help bees will continue to change over time is:
"Alger is still investigating whether increasing plant diversity or culling certain plants could help decrease disease transmission."
Reasoning: This statement suggests that ongoing research and investigation into the best practices for helping bee populations are occurring. Because Alger is still looking for answers regarding the impacts of plant diversity and which plants to cultivate, it indicates that current advice may be revised or updated as new findings emerge. This supports the notion that guidance on how to assist bees may adapt over time in response to evolving understanding of ecological interactions and disease dynamics.
