The correct response is:

**It only works for organisms that died less than about 60,000 years ago.**

Carbon dating, or radiocarbon dating, is effective for dating organic materials that are up to approximately 60,000 years old. Beyond this range, the amount of carbon-14 left becomes too small to measure accurately.
