Task 1 and task 2 involve creating two different methods.

The one you create for task 1 should be left as-is after you pass task 1.

The methods have different signatures (both arguments and return types). They also have different names, one is GetVideoGames (plural), and the other is GetVideoGame (singular).

Thank you so much ! i didn't realize til now
