Indexes does start at 0, but that means that indexes are one less than you might expect them to be, not one above. Item 1 is at index 0, item 2 at index 1, item 3 at index 2, item 4 at index 3, item 5 at index 4.

So you have to use [4] to retrieve the fifth item, which is the item the task asks you to retrieve.
