What Is the Benefit of Using Carbon in Radioisotope Dating,versus

Multiple Choice

What is the benefit of using carbon in radioisotope dating,versus using other elements?

A) The relatively longer half-life of carbon allows more accurate dating when samples are within the last ~55,000 years.
B) The longer half-life of carbon compared with other elements allows more precision in dating,especially for contaminated samples.
C) Carbon is relatively rare on Earth,so the presence of carbon can lead researchers to surprising findings compared with other elements.
D) Carbon is central to nearly all molecules in living organisms,and its ubiquitous presence in the atmosphere,plus shorter half-life,provides accurate dating of especially recent samples.
