I gave my students this multiple choice question: Scientists often work together to solve a problem. Sometimes they work in laboratories. Sometimes they are outside doing fieldwork. The chart provides a list of some careers in science. Which scientists might work together to save a polluted wetland?

Only one answer is correct among these 4 choices:
- chemist, botanist and ecologist
- astronomer, ecologist and physicist
- physicist, paleontologist and chemist
- botanist, astronomer and paleontologist

Could you tell me which one is correct?

chemist, botanist and ecologist
