Fluoride enters groundwater when rain dissolves minerals with fluoride in the soil. Researchers found that when all variables are held constant, fluoride concentrations are significantly higher in areas where the groundwater also contains a high concentration of sodium.

When there is a high concentration of fluoride, there is likely a high concentration of sodium.

Sodium helps dissolve fluoride into groundwater.

The stimulus does not provide alternative sources of fluoride in groundwater

This is anti-supported. The stimulus explains that rainfall causes minerals with fluoride to dissolve and enter the groundwater

There is no information in the stimulus to support this comparative statement. There is no information about the rate at which sodium vs fluoride dissolves

The stimulus explains that fluoride concentrations are higher in areas with high sodium concentrations, even when all variables are held constant. This suggests that the sodium could impact the rate at which minerals with fluoride dissolve.

This has the logic flipped. It is conceivable that high concentrations of fluoride minerals are found in areas with high concentrations of salt, not the other way around.
