The Book of Eden Chapter 4 covers not "the Fall" but "The Attack!" Satan-in-the-serpent spoke to them both at the Tree using plural pronouns every time. Each one ate. But each one ate differently. See how they each responded to God very differently too. You just might change your opinion about the woman.
There were three at the Tree in The Garden of Eden: the serpent-tempter, the woman and the man. Satan attacked both of the humans using plural pronouns for "you-both."
There were two very different responses by the humans. Sadly, a very incorrect idea is held in popular opinion. People look on the woman as the bigger sinner. Both ate. Both died. But only one rebelled against God and was disobedient to God's word. That was the man, not the woman.
There are more eye-opening distinctions to consider in this episode on Genesis 3:1-13.
