Jerry is an archaeologist working at a dig. He and his team found tools that were used by a civilization that, through carbon dating, is estimated to have lives 20,000 years ago. One year later, Jerry told his daughter about the artifact and she asks if now the artifact is 20,001 years old. Is she correct?
Why or why not? (1 point)
O Yes because this is the best approximate estimate that can be made.
No because the age of the artifact is approximated to be 20,000 years old, it is not a perfectly accurate measurement.
• Yes because carbon dating is perfectly accurate to the exact year.

No because artifacts age differently when they are buried beneath the surface, as compared to when they have been excavated.
No because the age of the artifact is approximated to be 20,000 years old, it is not a perfectly accurate measurement.
