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 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.
