ALL very confusing and takes me centuries to learn.
Absolutely! "Cartii" means the book'S, "cartea" means just THE book. Also, "carte" means book. There are very subtle differences between words but they are very important.The option "Marul este peste carte" should also be accepted since "peste" is a synonime for "deasupra". I see that in this course it is not yet accepted but you can 100% use this version, native speaker here ^^ Goodluck! :)
The explanations of the genitive are fantastic. However, the sentence "the apple is over the book" is still very strange. Is the apple jumping over the book in some kind of steeplechase? Or have the apple and the book been in a romantic relationship, broken up and now the apple has managed to recover? As a native English speaker, this translation is mystifying!
