Answer:
The author's tone of voice made Gary feel: C. sad.
Explanation:
When we listen to someone speak, we tend to react to that person's attitude. Their tone of voice is one of the means through which they can convey how we are supposed to feel. If someone talks to you in a soothing, calming, and assuring tone, you will feel relieved. If someone uses a rapid, joyful tone, you may feel happy or excited. In Gary's case, the orator used a quiet, somber tone of voice when talking about the economy, which most likely means he was talking about something serious and difficult. With that in mind, we can say Gary felt sad while listening to it.
