Elena wrote the following code in Scratch to have the sprite move and then turn around. However, the code does not work as expected. What should be done to fix the error? Change "move 20 steps" to "move 10 steps"
Change "turn left 180 degrees" to "turn left 90 degrees"
Change "turn left 90 degrees" to "turn right 180 degrees"
Change "turn right 90 degrees" to "turn left 90 degrees"
