Front

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

Back

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

Front

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

Back

Two times.

Front

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

Back

Integers.

Front

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

Back

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

Front

How can the following example be simplified by using a [Repeat] block? Options: 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).

Back

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

Front

When will the VR Robot move the VR Pen up? Options: 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.

Back

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