Determine whether the following disputes are verbal, factual, or some combination of the two. If verbal, discuss whether the dispute arises from vagueness or ambiguity.
ANTHONY: The sun is much smaller than the earth. You see, it's just a small thing up there in the sky. Therefore, since the sun's gravitational attraction is proportional to its mass, the sun's gravity is less than the earth's.
CINDY: You are as stupid as they come. I agree the mass of the sun is less than that of the earth, but its volume is greater. Therefore, since gravitational attraction is proportional to volume, the sun's gravity is greater than the earth's.
