Passage 2 - The Dentist

One day, Leroy notices a pain in his gums in the back of his mouth. He rubs his cheek and hopes it will go away. Unfortunately, it doesn't. Five days later, the pain is still there, and it is getting worse. Leroy determines that it is his tooth that is causing the pain. It aches and aches. It hurts so bad that Leroy starts to have trouble sleeping. A few more days pass and Leroy decides he's had enough, so he goes to the dentist. Leroy sits in the dentist chair. The dentist fastens a piece of paper around Leroy’s neck, puts on protective glasses, pulls a mask over her face, and uncovers her tools. She has a light, a mirror, and a drill. The dentist shines the light in Leroy’s mouth. She looks at the teeth in the very back of Leroy's mouth in the mirror. She finds the sore tooth and reaches for the drill. Leroy gets nervous when he hears the noise it makes, but the doctor reassures him that everything is fine. After fifteen minutes, the dentist fixes Leroy’s tooth.

Answer 1

According to the passage, the dentist uses the following tools:

I. a light
II. a mirror
III. a drill

The passage does not mention a brush or a saw, so the correct answer doesn't include those items. Thus, based on the provided options, the tools used by the dentist are a light (I), but neither a brush (II) nor a saw (III) is specifically mentioned as being used by the dentist.
