What do non-waiting blocks do in a VEXcode VR project?

• They repeat a behavior forever.

• They skip the next block in the stack.

• They allow the stack to continue even if the block's behavior is not yet complete.

• They should only be used in an emergency.

Which statement is TRUE for waiting blocks?

• They wait for the user to select the "Step" button.

• They wait until the VR Robot has enough power to complete the task.

• They allow the rest of the stack to continue even if that block's behavior has not been completed.

• They pause the stack until that block's behavior has been completed.

What does the highlighting feature do when a waiting block is being executed?

• A highlight will appear around the block until the behavior is complete.

• It will change colors depending on whether the project is running a waiting or non-waiting block.

• It will move to the next block to show the next behavior in the project.

• A highlight will stay on the block until the entire project is complete.

What types of values does the [Wait until] block accept?

• Boolean values: TRUE or FALSE.

• Numeric values: one - ten.

• Color values.

• Time values.

How often will the [Wait until] block check a Boolean condition?

• It will check repeatedly until the Boolean reports FALSE.

• It will check repeatedly until the Boolean reports TRUE.

• It will check once every minute until the project is complete.

• It will check only once.
