I'm still unsure about what casting does :/

also what does "Object object : list" mean again?

Casting is just "playing pretend" with the compiler. It's like you are telling the compiler: "let's pretend that this thing is a (your casting type here) instead of what it really is". One use of it is to allow you to access properties that are not part of the declared class, as illustrated in the other questions of this quiz.

And "Object object : list" means that within the loop, each item of the "list" will be aassigned to an Object named "object", one at a time.
