Chose the best answer based on the situation:

Troubleshooting Basics:
1.  The light sensor is emitting a red beam, the robot is not reacting correctly to certain colors or shades.
     a.  ambient light may be affecting the reading
     b.  ambient light may be affecting the reading, the distance between the sensor and the object is not close enough
     c.  Is it suppose to be generating its own light or read ambient light?

2.  The ambient noise on the sound sensor is being picked up.  It doesn't hear me.
     a.  calibrate sensor for ambient noise levels through the programming
     b.  don't use the sound sensor at all
     c.  tell everyone to be quiet

3.  Using the light sensor, the robot is suppose to read a red line and can't tell the difference between the green line and red line.
     a.  because the light sensor reads shades from black to white colors appear as black
     b.  because the light sensor reads shades from black to white the red and green may be the same shade of grey
     c.  because the light sensor reads colors, it should pick it up as different colors meaning the light sensor is broken

4.  The ultrasonic sensor is being used on a robot.  But it is consistently reading 4 inches or 10.16 cm.
     a.  check the angle of the sensor things may be in the way
     b.  things on the robot are in the way of the conical shaped signal
     c.  another sensor is interfering or something on the robot is in the way of the signal

5.  The touch sensor is being pushed in.  The robot reaction is not happening.
     a.  check program for setting of bump or press or unpress
     b.  is sensor suppose to be pushed in?
     c.  set the program for press and upload to NXT

6.  The robot rolls beyond 1 rotation and yet it's set for 1 rotation.
     a.  calibrate the rotation sensor
     b.  set your motor block in your program for brake and not coast
     c.  the sensor is broken
