Answer:
"She thinks about pretending to be sick to avoid the situation, but she goes to school and tells Kayla that she doesn't feel comfortable cheating and refuses to give Kayla the answers."
Explanation:
"Eventually Kayla realizes that cheating is wrong, and she and Emma make up." is a falling action, something that happens as a result, or towards the end of the story.
"Kayla asks Emma if she can copy her answers during the test." is building up to the climax, but its not quite there yet.
"Kayla and Emma are best friends, and they're at Emma's house studying for a chemistry exam" is just the introduction of the story. It's how the story starts off.
Thus, it leads to our final answer. "She thinks about pretending to be sick to avoid the situation, but she goes to school and tells Kayla that she doesn't feel comfortable cheating and refuses to give Kayla the answers." is where the action and conflict is most present. Therefore, it must be the answer!
