Which of the following describes why a Repeat block would be used in a project?

• To repeat certain blocks forever.

• To save space and time for blocks that repeat more than once in a project.

• To only run a stack of blocks one time.

• To run an attached stack of blocks when the project is started.

What behavior will the VR Robot perform if the condition of the Left Bumper Sensor being pressed is TRUE?

• The VR Robot will continue to drive forward.

• The VR Robot will drive in reverse for 50 millimeters (mm) and then turn left for 90 degrees.

• The VR Robot will stop moving.

• The VR Robot will drive forward for 50 millimeters (mm) and then turn right for 90 degrees.

Which of the following best explains why a [Repeat until] block was used in this project instead of a [Wait until]?

• A [Wait until] block would block the project flow.

  The Robot would be waiting to detect red before doing anything else.

• Using a [Repeat until] block allows the robot to drive forward for 300 millimeters (mm) and then turn right for 90 degrees, forever.

• Using a [Wait until] block checks for red after every robot move, which is not needed.

• Using a [Repeat until] block allows the [If then else] block to be skipped. This allows the project to execute faster

How can the following example be simplified by using a [Repeat] block?

• By placing the drive forward and turn blocks in a [Repeat] block that repeats four times.

• By placing the drive forward block in a [Repeat] block that repeats four times.

• By placing the turn block in a [Repeat] block that repeats four times.

• By changing all of the parameters of the drive forward blocks to 400mm instead of 200 mm.

Which of the following is the best description of what the VR Robot will do based on this project?

• The VR Robot will drive forward 1000 millimeters (mm) at maximum velocity. It will turn right 180 degrees, set velocity back to the default, and drive forward 1000 millimeters (mm).

• The VR Robot will drive forward 1000 millimeters (mm) at maximum velocity. It will turn right 180 degrees and drive forward 1000 millimeters (mm).

• The VR Robot will drive forward 1000 millimeters (mm) at maximum velocity. It will turn right 90 degrees, set velocity back to the default, and drive forward 1000 millimeters (mm).

• The VR Robot will drive forward 1000 millimeters (mm) at maximum velocity. It will turn left 180 degrees, set velocity back to the default, and drive forward 1000 millimeters (mm).

How long will the left motor spin?

• It will not spin

• 2 seconds

• 4 seconds
