it's about abusing the system, staying here for 5 years using visa runs every 6 months. Am I an officer? Of course not. Can an immigration officer not let you in even if you have a legit visa? YES, IT' UP TO HIM! No matter what questions they ask, the fact is that if they do, you could even get a 60-day , or even worse, not be allowed to enter... try to see the big picture, it's not that hard... and use common sense, and you'll never be wrong".... btw, if you are curious about questions, so maybe you can understand better the big picture: "why don't you go home to see your family? Do you love your family?" I wish now everything is much clear for you...
