What is the first step in coding the VR Robot to move the VR Pen down to draw a black line?

• [Drive for] block set to 2000 millimeters (mm).

• Drag the [Turn for] block into the workspace and set the parameter to "400 millimeters (mm)".

• Drag the [move pen] block into the workspace and use the drop-down menu to set the position to "down".

• Drag the [move pen] block into the workspace and use the drop-down menu to set the position to "up".

What is the first step in coding the VR Robot to draw a red line?

• Drag the [Set Pen color] block into the workspace and use the drop-down menu to set the color to "red".

• Drag the [move pen] block into the workspace and use the drop-down menu to set the position to "up".

• Drag the [Turn for] block into the workspace and set the parameter to "200 millimeters (mm)".

• Drag the [Set Pen color] block into the workspace and use the drop-down menu to set the color to "blue".

How many times will the [Repeat] block repeat the [Turn for] and [Drive for] blocks inside of it?

• Only once

• Two times

• Three times

• Four times

What types of values can the [Repeat] block accept as parameters?

• Decimal values

• Negative values

• Words or text

• Integers

What is the condition that will end this [Repeat] block?

• After the VR Robot places the pen down.

• After the VR Robot drives forward one time for 200 millimeters (mm).

• After the [Repeat] block has repeated the blocks inside of it four times.

• After the VR Robot has driven forward 200 millimeters (mm) then turned right 60 degrees six times.

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

• By placing the [Drive for] and [Turn for] blocks in a [Repeat] block that repeats four times.

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

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

• By changing all of the parameters of the [Drive for] blocks to 400 millimeters (mm) instead of 200 millimeters (mm).

When will the VR Robot move the VR Pen up?

• Before the [Repeat] block has repeated all of the blocks inside of it twice.

• Before the VR Pen is set to the color red.

• After the [Repeat] block has repeated all of the blocks inside of it six times.

• After the [Repeat] block has repeated all of the blocks inside of it twice.
