Question

which statement primarily appeals to ethos, or character, to support the position that wearable fitness trackers can improve peoples health?
imagine seeing your step count at the end of each day, feeling triumphant when you hit a lofty goal and determined to work harder when you fall short.
i have been wearing a pedometer for several months, and knowing how far i am walking each day has brought about an increase in my cardiovascular fitness.
as so much about our bodies is unknown to us throughout the day—such as heart rate and blood sugar levels—it follows that increasing awareness of these factors will give us helpful insights into how to improve our health.

Explanation:

Para determinar cuál declaración apela a ethos (carácter o credibilidad), debemos identificar la que usa experiencia personal para establecer credibilidad. La primera usa pathos (emoción), la tercera usa logos (razonamiento). La segunda declaración ("I have been wearing a pedometer...") comparte una experiencia personal, lo que construye credibilidad al mostrar que la persona ha probado el rastreador y ha visto mejoras, lo que es un llamado a ethos.

Answer:

The statement: "I have been wearing a pedometer for several months, and knowing how far I am walking each day has brought about an increase in my cardiovascular fitness." (This statement appeals to ethos by sharing a personal experience to establish credibility about the effectiveness of fitness trackers.)
