Scratch quiz CS first

Salomon programmed three sprites with the code above, but they all move in exactly the same way. What can he add to the three sprites' code to make them move differently each time the program is run?

• A "pick random" block

• A "move -10 steps" block

• A "turn 45 degrees" block

• A "turn -5 degrees" block

What you run the program above, what happens? (choose the best answer)

• The sprite says "Hello!" for 2 seconds

• The sprite says "Hello!" if the pick random block equals 2

• The sprite will never say hello because the pick random block cannot equal 2

• The sprite will never say hello because this code doesn't use a forever loop
