3. The correct answer is B.

The dentists argue that adding fluoride to tap water lulls people into

a false sense of dental security because they rely too heavily on the

fluoride to do work they should do for themselves. This argument,

added to the water. If this were not the case, the argument would

be seriously weakened because the dentists could not claim that

people rely in the fluoride. Only choice B addresses this.
