Final answer:
The writer has used emotional appeal as the primary means to convey her message, particularly through sharing personal experiences of students, thereby appealing to the audience's pathos. The use of statistical data for logical evidence and credible sources also adds to the ethos appeal.
Step-by-step explanation:
In this article, the writer has primarily used emotional appeal to convey her message, which can be identified as an appeal to pathos. By sharing the experience of a student struggling with anxiety and depression, the writer aims to show compassion and arouse audience empathy.
The use of emotional appeal is meant to target the readers' emotions, potentially urging them to understand and support the argument for expanded mental health services. Moreover, the establishment of credibility through interviewing a campus mental health counselor, and referencing data from the International Association of Counseling Services, also contributes to the ethos aspect of the argument. However, the primary technique as per the provided context appears to be the emotional connection established with the audience.
Additionally, although not the main focus in the provided context, there is a mention of using statistical data as logical evidence or appeal to logos, which could further substantiate the argument. The presence of credible evidence from reliable sources suggests a rational underpinning to the writer's argument. It is the combination of emotional narratives with factual evidence that powerfully conveys the writer's message and persuades the audience.
