Programming 101

1. What does the following code block do?
{"func":"blockSensingAskChoices","values":[{"type":"string","value":""},{"type":"string","value":""}]}

• Allows you to ask a question that has multiple choice answers
• Asks a question where the user just types in the answer
• Creates an entire quiz for you, with random questions
• Is the exact same as a {"func":"blockLooksSay","values":[{"type":"string","value":""}]} block

2. A bee Actor is flying around the screen and has the code below. When will the bee say "Hooray!"?
{"func":"registerTrigger","values":[{"type":"wrapper","func":"valueSensingTouchingSprite","values":[{"type":"string","value":"Flower"}]}],"next":{"func":"blockLooksSay","values":[{"type":"string","value":"Hooray!"}]}}

• Each time it touches the flower
• All the time
• Never
• While it is not touching the flower

3. Why is a {"func":"blockControlIfElse","values":[{"type":"boolean","value":""}],"containers":[null,null]} block like a split in the road?

• If one thing happens, you go one way; if another thing happens, you go a different way
• You should use it when your Actors are walking on a path
• There is only one option for what could happen
• It makes Actors move like they are walking on a path

4. True or False: The first part of the {"func":"blockControlIfElse","values":[{"type":"boolean","value":"true"}],"containers":[null,null]} block is the 'true' path, and the second part is the 'false' path.

• True
• False

5. True or False: The {"type":"wrapper","func":"valueSensingAnswer"} block stores the questions of your quiz.

• True
• False

6. An Actor has the code shown below. If it is not sunny, what will this Actor do? {"func":"blockControlIfElse","values":[{"type":"wrapper","func":"valueVar","name":"isSunny?"}],"containers":[{"func":"blockControlCall","cat":"functions","name":"Go To Beach","label":"Go To Beach"},{"func":"blockControlCall","cat":"functions","name":"Stay Home","label":"Stay Home"}]}

• Stay home
• Go to the beach
• Go to the beach and stay home
• Neither

7. Why is the {"func":"blockControlIfElse","values":[{"type":"boolean","value":"true"}],"containers":[null,null]} block useful for making quizzes?

• You can use it to do one thing if the user got the answer right and a different thing if the user got the answer wrong
• It automatically generates a lot of questions for you
• It stores the user's answer for you
• It writes out your questions on the Stage

8. What does the {"type":"wrapper","func":"valueSensingTouchingSprite","values":[{"type":"string","value":""}]} code block return?

• True or false, depending on whether your Actor is touching the parameter
• The name of the Actor your Actor is touching
• It doesn't return anything; it makes your Actor go touch the Actor in the parameter
• It returns the number of Actors that your Actor is touching

9. Which of the following blocks is an Event block?

• {"func":"registerTrigger","values":[{"type":"boolean","value":""}]}
• {"func":"blockControlIfElse","values":[{"type":"boolean","value":""}],"containers":[null,null]}
• {"type":"wrapper","func":"valueSensingTouchingSprite","values":[{"type":"string","value":""}]}
• {"func":"blockControlRepeat","values":[{"type":"number","value":""}],"containers":[null]}

10. Caren is making a quiz program. She wants the quiz to ask addition questions, but wants the questions to be made randomly. Which of the following code blocks will ask a random addition question?

• {"func":"blockSensingAskAndWait","values":[{"type":"string","value":"What is"},{"type":"wrapper","func":"valueOpRandom","values":[{"type":"number","value":"1"},{"type":"number","value":"10"}]},{"type":"string","value":"+"},{"type":"wrapper","func":"valueOpRandom","values":[{"type":"number","value":"1"},{"type":"number","value":"10"}]},{"type":"string","value":"?"}]}
• {"func":"blockLooksSay","values":[{"type":"wrapper","func":"valueOpRandom","values":[{"type":"number","value":"1"},{"type":"number","value":"10"}]}]}
• {"func":"blockSensingAskAndWait","values":[{"type":"string","value":"What is"},{"type":"string","value":"2"},{"type":"string","value":"+"},{"type":"string","value":"2"},{"type":"string","value":"?"}]}
• None of the above
