Which ocean current is responsible for the warm, moist air? What type of current is it?

Gulf Stream

As these currents flow along the edges of continents, they affect the temperature of the coastal regions. Along the east coast of the U.S., the Gulf Stream carries warm water from the equatorial region to the North Atlantic Ocean, keeping the southeast coast relatively warm.

the answer is "d"

(context) if you were to travel to the middle east and go into peoples homes there would be like 4 generations in there

(more context) i'm pretty sure in the middle east they take loyalty and family bonds very serious

(last bit of context) i'm also positive that extended families are most commonly found in urban areas
