I think your assigned reading may have the answer that will be acceptable to your teacher. Various religious traditions interpret it in different ways. Some say the two versions in Genesis are complementary to each other, some say they contradict each other. I can offer you some further reading on the subject. One interpretation is that the first creation story describes the heavenly creation, the other the Earthly creation; two points of view.
If you are in a Christian school, there may be only one interpretation that is acceptable. If this is a more academic (impartial) study, your thoughts may be important to your teacher.
