Final answer:
False. A given agent cannot be perfectly rational in two distinct task environments.
Step-by-step explanation:
False
A given agent cannot be perfectly rational in two distinct task environments. This is because rationality is context-dependent and is influenced by the specific task and environment at hand.
For example, consider an agent who is rational in the task environment of playing chess. This agent may make strategic decisions and apply logical reasoning based on the rules and constraints of the game. However, if the same agent is placed in a completely different task environment, such as solving mathematical equations, their rationality may not be as effective or applicable.
