Hi! I would like to know when it is not possible to use the "'s" you add to the noun describing the owner. It is written in my grammar book that "the possessive case may also be used with animals, countries (and places) and expressions of time". But in the examples that follow, there are none of places that are common nouns. The two examples that involve places are : "Norway's oil production" and "California's climate". And what about inanimate things? For instance, can you say "the door's handle", or do you have to say "the handle of the door"? Could someone please give me precise details about that? Thanks a lot!
