1. choose the best answer.

what is a digital device worn over the eyes that produces a virtual reality experience?
smart workout machine
smart gym
fitness tracker
head - mounted display

Explanation:

• For question 3: Fitness apps like dietary ones need users to input data (caloric intake etc.), so it's manual data entry. "No" and "absent" don't make sense as data is provided. "Automatic" would imply no user input, but users have to enter details like what they ate.
• For question 4: A head - mounted display is a device worn over the eyes for virtual reality. A smart workout machine is for exercise, a smart gym is a facility, and a fitness tracker is usually worn on the body (like a wristband) not over the eyes.

Answer:

1. C. manual
2. D. head - mounted display
