Skeletal remains of early humans indicate clearly that our ancestors had fewer dental problems than we have. So, most likely, the diet of early humans was very different from ours.
Which one of the following, if true, most strengthens the argument?
A healthy diet leads to healthy teeth.
Skeletal remains indicate that some early humans had a significant number of cavities.
The diet of early humans was at least as varied as is our diet.
Early humans had a shorter average life span than we do, and the most serious dental problems now tend to develop late in life.
Diet is by far the most significant factor contributing to dental health.
