The function of a sensor is to:

1. detect changes in environment and send signals.
2. process the input data and make decisions.
3. change electrical energy into motion.
4. supply power to the robot.

The purpose of Turing Test is to evaluate:

1. memory consumption of a computer.
2. the processing speed of computers and humans.
3. two computer programs.
4. if a machine can exhibit human-like responses.

Assertion (A): Robots use actuators for movement.

Reason (R): Actuators sense the environment and convert it to electrical signals.

1. (A) is true but (R) is false.
2. (A) is false but (R) is true.
3. Both (A) and (R) are true and (R) is the correct explanation for (A).
4. Both (A) and (R) are true but (R) is not the correct explanation for (A).
