examine current species of plants and animals research past species in the library interview older scientists examine fossils records
I gave my students this multiple choice question: Paleontologists are scientists who study evidence of past life on Earth. Which method do paleontologists most likely use to determine the forms of life that existed millions of years ago?

Only one answer is correct among these 4 choices:
- examine current species of plants and animals
- research past species in the library
- interview older scientists
- examine fossils records

Could you tell me which one is correct?

examine fossils records
