Question

A bone is tested, and its C-14 to C-12 ratio is nearly identical to that of the bones of living animals. What can be said about the bone's absolute age?
a. It is 5,730 years old.
b. It is much less than 5,730 years old.
c. It is slightly less than 5,730 years old.
d. It is slightly more than 5,730 years old.

Answer 1

Answer=B

The half life of C-14 is 5,730 years. Seeing as the C-12 C-14 ratio is nearly the same, the tested bone is much younger than 5,730 years old.

Answer 2

B. It is much less than 5,750 years old.

Hope it helps.
