Which part of the passage is most clearly the conclusion?

The passage describes a series of events in which first Kayla and Emma are introduced as best friends, and then they interact under certain circumstances which leads to the story's conflict and then to its conclusion or outcome: The girls are studying for a Chemistry exam, when Kayla asks Emma, a straight-A student, if she can copy from her exam. This request, however, makes Emma feel distressed because she does not feel comfortable cheating: she does not sleep well, and she even considers the idea of pretending to be sick to avoid the situation. However, in the end, Emma decides to go to school and let Kayla know that she will not give her the answer. Consequently, Kayla fails the test and gets mad at Emma for a long time. Nevertheless, “Eventually Kayla realizes that cheating is wrong and she and Emma make up.” This last sentence is the conclusion of the passage because it is the one that expresses the outcome or the consequences of the series of events.
