← Language & CommunicationA robot processes spoken commands to manipulate objects in a shared workspace. If the referring expression 'put that there' is uttered, which consequence follows?
A)Ambiguity always halts task execution.
B)Successful task execution requires grounding.✓
C)Pronoun resolution always utilizes coreference.
D)Spatial relations remain underspecified always.
💡 Explanation
The robot must establish shared understanding of 'that' and 'there' through deixis, a form of reference dependent on context; otherwise, manipulation fails because the robot cannot uniquely identify the object or location. Grounding, not mere pronoun resolution, is needed; therefore successful task execution requires grounding, rather than relying solely on predefined spatial relationships.
