Answer:
My best guess, the zagros mountains itd be isolation and protection...the same for the Syrian desert. the Taurus mountains look like they have a river running through them so it could be isolation and protection, or isolation and irrigation.....(wouldn't isolation in turn mean protection??) I would think so....so I'd go with isolation and irrigation if it were me.
the Tigres and Euphrates would bother provide irrigation and transportation and trade as they have large rivers running through them
Because they knew they could do more and they would work because they knew they were getting money
