How does phoenix pass “the test” of the hunter? she accompanies him on his journey for a while. she him by giving him money she found on the ground. she stands her ground, even though he points a gun at her. she allows him to her out of the ditch.

With multiple choice questions like this one, you can use the process of elimination to help narrow down the possible answers. In reading the story, you know that Phoenix did not accompany the hunter on his journey, nor did she give him any money (she had no money herself). She did, however, accept his help getting out of the ditch, and she did face him down even as he pointed his gun at her. So you have two possible answers now. Think about which came first. In the story, the hunter helped Phoenix out of the ditch before pointing his gun at her and bullying her. Had she already passed his "test" by accepting his help, why would he then point the gun at her? That wouldn't really make sense. So for this question, the best answer is the third one, that she stood her ground even as he threatened her. After that moment, he let her walk away.
