Question 10
Many people with type 1 diabetes now wear a continuous glucose monitor. What does it do?
- A. replaces the pancreas
- B. makes insulin from glucose

- A. The pancreas releases insulin
- B. The thyroid stops working

- A. Person B, because glucose rose much higher and stayed high
- B. Person A, because glucose returned to normal
- C. Neither, because glucose always rises after a drink
