Q1
D — A turn block is measured in degrees, not steps. Steps are for the move block. It should say 'turn right 90 degrees'.
Q2
C — The move block counts steps, not degrees. Degrees are for turning. It should be 'move 100 steps' so the sprite draws the side of a square.
Q3
B — The go to block needs both an x number and a y number to know exactly where to put the sprite. It should be 'go to x: 0 y: 0'.
Q4
B — The script starts when the LEFT arrow key is pressed, so the sprite should turn left. The line should be 'turn left 15 degrees'.
Q5
C — The turn block must say which way to turn, right or left. It should be 'turn right 90 degrees'.
