Which of the following best explains why a [Repeat until] block was used in this project instead of a [Wait until]?

• Using a [Repeat until] block would block the project flow and thus, the condition of an object being detected, would never be checked. This will cause the VR Robot to not move.

• Using a [Wait until] block allows all conditions in the project to be checked forever. The Down Eye Sensor will constantly be checking the condition of detecting red. This will drive the VR Robot to eventually fall off of the Playground.

• Using a [Wait until] block would block the project flow. The VR Robot would be waiting until the Down Eye Sensor detected red before doing anything else. This would cause the VR Robot not to move.

• Using a [Repeat until] block allows the VR Robot to make more accurate turns, since the [Turn] block will repeat forever.

What is the best explanation for why a project would check for multiple conditions?

• Each additional condition allows the user to monitor an additional sensor in the Monitor Window.

• Each additional condition allows the VR Robot to check an additional sensor in the same project and use that data with the logic of the project.

• Each additional condition allows the user to track an additional sensor value in the Print Console.

• Each additional condition allows the VR Robot to monitor an additional sensor so that the VR Robot can never fall off of a Playground.
