Poor quiz interface

Hey, this isn't a question but rather a quick constructive critique.

The quiz right before this video has you enter commands with multiple arguments, such as "cat a.txt b.txt". The problem is that the quiz interface is set up rather poorly, because it actually dings you as incorrect and makes you retake the quiz if you type this exactly the way you should in the terminal, with a space between the arguments. Instead the quiz requires each argument to be entered in a different input field, so you have to tab or click over to the second field instead of just using a space.

It feels very awkward to have the quiz interface set up in this way that rejects your answer if you enter the command exactly the way it's supposed to work!
