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 (such as bones, wood, and shell) and is limited to approximately 60,000 years due to the half-life of carbon-14. After this time, the amount of carbon-14 remaining becomes too small to accurately measure.
