The calling format for removeChild is parent
.removeChild(child
);.
Conveniently, in task 1 you identified the parent element, and in task 2 you identified the child. So in task 3, you just need to construct the call by filling in the other variables in the right places.

21,610 PointsHello Steven, I can assure you I did not down-vote, and marked as best answer, so I assume you were indeed a victim! I have given you a +1 though, just to counter it ;)
