01 A student nods while listening to the teacher but keeps attention on a mobile phone. What does this show?
Answer and explanation
Correct answer: D. A single cue does not prove genuine attention
Explanation: The governing concept is that non-verbal communication should be interpreted through several cues and the surrounding context. Nodding can suggest agreement or attention, but looking at a mobile phone suggests divided attention. Therefore, option D is correct. Nodding alone cannot prove understanding; the other options incorrectly treat one gesture, the device, or distance as decisive evidence.
