Human activity, especially the burning of fossil fuels, has led to an increase in anthropogenic carbon dioxide emissions. This has caused a doubling in the concentration of CO2 in the atmosphere.

Based on the data shown in the graph, which of the following is the most plausible hypothesis for the cause of the trend in CO2 levels from about 5,000 years ago to the present?

Increased temperatures provide an expanded breeding range and duration, which will likely increase the size of vector populations.

Based on the information in the diagram, which of the following best supports the claim that a change in the duration of warm seasons would result in a higher prevalence of vector-borne diseases?

The Northeast and the Gulf of Mexico
