Show answer
Answer: D. Wearables such as smartwatches and fitness bands track location using GPS (item 1) and monitor sleep using motion and heart-rate sensors (item 2). Hearing aids and similar wearable devices help hearing-impaired people (item 3). So all three.
Watch for: Students forget that a hearing aid is itself a wearable device.
Why the other options are wrong
- A. Wrong because wearables also do sleep monitoring and hearing assistance.
- B. Wrong because wearables also identify location through GPS.
- C. Wrong because wearables also do location tracking and sleep monitoring.
