{"func":"blockLooksChangeSizeBy","values":[{"type":"number","value":"10"}]}

4. {"func":"blockLooksChangeSizeBy","values":[{"type":"number","value":"2"}]} What would happen when you changed the size by -2 instead of 2?

The racer would move backward instead of forward
The racer would grow even more than before
Nothing
The racer would shrink instead of grow

5. What's the difference between the {"func":"blockControlForever","containers":[null]} and {"func":"blockControlForeverIf","values":[{"type":"boolean","value":"false"}],"containers":[null]} blocks?

The 'Forever' block will run until the end of the program, while the 'Forever if' block will run as long as its condition is satisfied
The 'Forever if' block will run until the end of the program, while the 'Forever' block will run as long as its condition is satisfied
The 'Forever' block and the 'Forever if' block will both run even after the program finishes
The 'Forever' block will run after the program finishes, while the 'Forever if' block will run as long as its condition is satisfied

6. {"func":"registerFlagTrigger","next":{"func":"blockControlForeverIf","values":[{"type":"wrapper","func":"valueSensingKeyPressed","values":[{"type":"choice","value":"space"}]}],"containers":[{"func":"blockPenUp","next":{"func":"blockControlRepeat","values":[{"type":"number","value":"10"}],"containers":[{"func":"blockControlWait","values":[{"type":"number","value":".2"}],"next":{"func":"blockLooksChangeSizeBy","values":[{"type":"number","value":"10"}]}}],"next":{"func":"blockControlRepeat","values":[{"type":"number","value":"10"}],"containers":[{"func":"blockLooksChangeSizeBy","values":[{"type":"number","value":"10"}],"next":{"func":"blockControlWait","values":[{"type":"number","value":".2"}]}}],"next":{"func":"blockPenDown"}}}}]}} What would happen if you removed the pen up and pen down blocks?

The racer would draw a different color when it jumped
The racer would keep drawing when it jumped
The racer would stop drawing when it jumped
The racer would not be able to move

7. What would happen if you changed {"func":"blockControlRepeat","values":[{"type":"number","value":"10"}],"containers":[{"func":"blockLooksChangeSizeBy","values":[{"type":"number","value":"10"}],"next":{"func":"blockControlWait","values":[{"type":"number","value":".2"}]}}]} to {"func":"blockControlRepeat","values":[{"type":"number","value":"20"}],"containers":[{"func":"blockLooksChangeSizeBy","values":[{"type":"number","value":"10"}],"next":{"func":"blockControlWait","values":[{"type":"number","value":".2"}]}}]}?

The racer would not change size
The racer would shrink instead of growing

The racer would grow the same amount

8. What would happen to the racer's path if you replaced {"func":"registerFlagTrigger","next":{"func":"blockControlForeverIf","values":[{"type":"wrapper","func":"valueSensingKeyPressed","values":[{"type":"choice","value":"space"}]}],"containers":[{"func":"blockPenUp","next":{"func":"blockControlRepeat","values":[{"type":"number","value":"10"}],"containers":[{"func":"blockLooksChangeSizeBy","values":[{"type":"number","value":"10"}],"next":{"func":"blockControlWait","values":[{"type":"number","value":".2"}]}}],"next":{"func":"blockControlRepeat","values":[{"type":"number","value":"10"}],"containers":[{"func":"blockLooksChangeSizeBy","values":[{"type":"number","value":"-10"}],"next":{"func":"blockControlWait","values":[{"type":"number","value":".2"}]}}],"next":{"func":"blockPenDown"}}}}]}} with {"func":"registerFlagTrigger","next":{"func":"blockControlForeverIf","values":[{"type":"wrapper","func":"valueSensingKeyPressed","values":[{"type":"choice","value":"space"}]}],"containers":[{"func":"blockPenSetColor","values":[{"type":"color","value":"#ff00ff"}],"next":{"func":"blockControlRepeat","values":[{"type":"number","value":"10"}],"containers":[{"func":"blockLooksChangeSizeBy","values":[{"type":"number","value":"10"}],"next":{"func":"blockControlWait","values":[{"type":"number","value":".2"}]}}],"next":{"func":"blockControlRepeat","values":[{"type":"number","value":"10"}],"containers":[{"func":"blockLooksChangeSizeBy","values":[{"type":"number","value":"-10"}],"next":{"func":"blockControlWait","values":[{"type":"number","value":".2"}]}}],"next":{"func":"blockPenSetColor","values":[{"type":"color","value":"#00ff00"}]}}}}]}}?

The path would still disappear when the racer jumps

The racer would only shrink

14. What is the difference between {"func":"registerFlagTrigger","next":{"func":"blockControlForeverIf","values":[{"type":"wrapper","func":"valueSensingKeyPressed","values":[{"type":"choice","value":"space"}]}],"containers":[{"func":"blockControlRepeat","values":[{"type":"number","value":"10"}],"containers":[{"func":"blockLooksChangeSizeBy","values":[{"type":"number","value":"2"}],"next":{"func":"blockControlWait","values":[{"type":"number","value":".2"}]}}],"next":{"func":"blockControlRepeat","values":[{"type":"number","value":"10"}],"containers":[{"func":"blockLooksChangeSizeBy","values":[{"type":"number","value":"-2"}],"next":{"func":"blockControlWait","values":[{"type":"number","value":".2"}]}}]}}]}} and {"func":"registerKeyTrigger","values":[{"type":"choice","value":"space"}],"next":{"func":"blockControlRepeat","values":[{"type":"number","value":"10"}],"containers":[{"func":"blockLooksChangeSizeBy","values":[{"type":"number","value":"2"}],"next":{"func":"blockControlWait","values":[{"type":"number","value":".2"}]}}],"next":{"func":"blockControlRepeat","values":[{"type":"number","value":"10"}],"containers":[{"func":"blockLooksChangeSizeBy","values":[{"type":"number","value":"-2"}],"next":{"func":"blockControlWait","values":[{"type":"number","value":".2"}]}}]}}}?

The two code blocks do the same thing
The first block will make the racer jump as soon as the program starts, while the second block will make the racer jump only when space is pressed
The first block will not make the racer jump, while the second block will make the racer jump only when space is pressed
Neither of the blocks will make the racer jump

15. What would happen if you replaced {"func":"registerFlagTrigger","next":{"func":"blockControlForeverIf","values":[{"type":"wrapper","func":"valueSensingKeyPressed","values":[{"type":"choice","value":"space"}]}],"containers":[{"func":"blockControlRepeat","values":[{"type":"number","value":"10"}],"containers":[{"func":"blockLooksChangeSizeBy","values":[{"type":"number","value":"2"}],"next":{"func":"blockControlWait","values":[{"type":"number","value":".2"}]}}],"next":{"func":"blockControlRepeat","values":[{"type":"number","value":"10"}],"containers":[{"func":"blockLooksChangeSizeBy","values":[{"type":"number","value":"-2"}],"next":{"func":"blockControlWait","values":[{"type":"number","value":".2"}]}}]}}]}} with {"func":"registerFlagTrigger","next":{"func":"blockControlForeverIf","values":[{"type":"wrapper","func":"valueSensingMouseDown"}],"containers":[{"func":"blockControlRepeat","values":[{"type":"number","value":"10"}],"containers":[{"func":"blockLooksChangeSizeBy","values":[{"type":"number","value":"2"}],"next":{"func":"blockControlWait","values":[{"type":"number","value":".2"}]}}],"next":{"func":"blockControlRepeat","values":[{"type":"number","value":"10"}],"containers":[{"func":"blockLooksChangeSizeBy","values":[{"type":"number","value":"-2"}],"next":{"func":"blockControlWait","values":[{"type":"number","value":".2"}]}}]}}]}}?

The racer would jump whenever the mouse is pressed
The racer would jump whenever space is pressed
The racer would not be able to jump
The racer would jump as soon as the program starts

16. What is the size of the pen after running this code block? {"func":"blockPenSetSize","values":[{"type":"number","value":"40"}],"next":{"func":"blockPenChangeSize","values":[{"type":"number","value":"10"}]}}

17. What would the line drawn by an Actor with this code block look like? {"func":"registerFlagTrigger","next":{"func":"blockPenSetColor","values":[{"type":"color","value":"#00ff00"}],"next":{"func":"blockPenDown","next":{"func":"blockControlForever","containers":[{"func":"blockPenChangeHue","values":[{"type":"number","value":"10"}]}]}}}}

It would be a rainbow line
It would be a green line
It would be a blue line
It would be a black line

It would make the Actor move in a circle when the mouse is down
It would make the Actor follow the mouse pointer when the mouse is down
It would make the Actor spin when the mouse is down
It would make the Actor draw a square when the mouse is down

20. Quentin is trying to make an Actor grow larger after collecting a power-up. Which of these blocks does he need in his code?
