In the context of digital technologies for entertainment, consider the following statements:1.In Augmented Reality (AR), a simulated environment is created and the physical world is completely shut out.2.In Virtual Reality (VR), images generated from a computer are projected onto

A 1 and 2 only
B 3 and 4 only
C 1, 2 and 3
D 4 only

Correct answer: (b) 3 and 4 only

Explanation

  1. A

    1 and 2 only

    (a) 1 and 2 only. Statement 1 describes VR, not AR: AR does not shut out the physical world. Statement 2 describes AR (computer images on real surroundings), not VR. Both labels are swapped. Not the key.

  2. B

    3 and 4 only

    (b) 3 and 4 only. AR keeps the user in the real world and overlays simulated content. VR transposes the user into a generated scene and takes over vision (typically via a headset). Statements 1 and 2 are reversed. That pair is the official key.

  3. C

    1, 2 and 3

    (c) 1, 2 and 3. Statements 1 and 2 are false. Not the key.

  4. D

    4 only

    (d) 4 only. Statement 3 is also true. Dropping AR’s correct description is not the key.

Summary. Official key is (b). AR overlays; VR immerses. Statements 1 and 2 swap the two technologies. Statements 3 and 4 state the standard distinction. Honour (b).
