To determine which evidence best supports the analysis, it is important to focus on the relevance and strength of the data in relation to the conclusion being drawn.
If the analysis refers to the impact of viruses on honeybees or the relationship between virus presence and the environment (such as flowers or proximity to apiaries), the evidence that would best support that analysis is:
the percentage of flowers that tested positive for viruses and their proximity to apiaries.
This evidence directly relates to the environmental factors surrounding the honeybee apiaries, which could illustrate how the presence of viruses in flowers affects the health of bees in those areas.
