- 5. Multiple Choice
How does the X coordinate value change as the VR Robot moves forward in this project on the Numbered Grid Map Playground?
It decreases as the VR Robot drives forward.
It increases as the VR Robot drives forward.
It remains -800 millimeters (mm) as the VR Robot drives forward.

- 6. Multiple Choice
This project is intended to drive to number '6' on the Number Grid Map Playground but does not work. Number '6' has the coordinates X: 50 and Y: -900. What is the error?
The <Less than> block should be set to -900 not 50.
This project should use a <Greater than> block instead of a <Less than> block and be set to -900.
The <Less than> block should be set to -900 not 50.
This project should use a <Greater than> block instead of a <Less than> block and keep the same parameters.
- 7. Multiple Choice
