Answer:
The answer to the question: A fossil is determined through radioactive dating to be 1.5 million years old. This is an example of, would be: A: Absolute dating.
Step-by-step explanation:
In paleontology, there are two ways in which fossils can be dated. One, is the inaccurate one, called relative dating, in which other sources, most commonly rocks around the fossil, as well as other fossils called index fossils, are used to approximately date a target fossil. But the more accurate, and almost infalible one, is called, absolute dating. This one uses radioactive isotopes and their characteristics in rocks and in the fossil itself, to more accurately establish the age of the fossils. The technique measures these isotopes in the minerals and components in the rocks and fossils to determine date.
