ROS in 5 Days, Debugging Tools Quiz

There is a question on this quiz concerning RVIZ and what can be visualized. I am fairly certain I have gone through each answer by now, and they all appear to get marked wrong. Is it possible to double check to see if there is a bug on the quiz? If not, I may have just forgotten that I got it correct, and I have been trying alternatives to no success.

Hey Mike,

Thank you for pointing this out. There was a bug and it has been fixed.

Thanks again!
