"I am going to try taking melatonin to get to sleep at night," Tamia said. "I read somewhere that since it is a chemical our bodies produce naturally, it's much safer to use than other sleep aids."
"Hmm, it's funny that you should mention that. I recently read a study from Massachusetts Institute of Technology that said those melatonin supplements they sell at the drug store can contain almost ten times the amount your body needs to achieve quality sleep," Aubrey responded.

What method does Aubrey use to persuade Tamia?

Aubrey actually uses both Ethos and Logos to persuade Tamia. She uses Ethos when referencing the study from Massachusetts Institute of technology. Referencing a credible institute helps to gain Tamia's trust. She uses Logos when explaining the study, stating that drugstore melatonin supplements contain ten times as much as necessary for quality sleep. This helps to appeal to Tamia's logic; the use of fact and numberical info helps her to think logically about the supplements.

im pretty sure a would be the answer
