Answer 1

The correct statement about the effectiveness of carbon dating 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 (like bone, wood, or shells) that are up to about 50,000 to 60,000 years old. Beyond this time frame, the amount of carbon-14 remaining becomes too small to measure accurately.
