What will happen to the size of the sprite if you put the “change size by 50” block inside a forever loop and start the program, as shown in the script below? Assume the sprite is at its usual size (Picture A) when the program starts.
The sprite will grow to the size shown in Picture B and then stop changing.
The sprite will grow to the size shown in Picture B, then shrink back to the size shown in Picture A, and then stop changing.
The sprite will grow to the size shown in Picture B, then shrink back to the size shown in Picture A, and keep doing this over and over again until the program is stopped.
The sprite will keep growing and growing and will eventually fill the entire stage.
The next few questions will ask you questions about a sprite as it moves across the stage. In the pictures, each square is one step. The sprite’s path will be shown in blue. Turns will be shown with a little blue arrow in the corner.

Look at the script in the image, which will control the sprite on the grid to the right. Each square is one step.
The sprite is in the top left corner of the grid when the green flag is clicked. Where will the sprite stop moving?
On the square marked with the letter A.
On the square marked with the letter B.
On the square marked with the letter C
The sprite will not stop moving. The sprite will go to A, then B, then C, then back to the corner and keep doing that again and again until the program is stopped.
The sprite will not stop moving. The sprite will walk to A and then keep walking straight off the edge of the grid until the program is stopped.
