Continental and maritime air masses can be divided into three more categories. These categories are based on the temperature of the surface over which they originated. What are these three temperature-based categories?

Three temperature-based categories are hot, cold and moderate. Continental cold (CTc), continental hot (CTh) and maritime cold (MTc), and maritime hot (MTh) are important.

Explanation:

Air mass refers to the presence of thick dense heavy air on the above of ground surface in stable condition. Where cold and warm air contrast that place is ideal for the creation of air mass. Air mass is of four types: continental, maritime, tropical and polar.

These air masses again divided into sub parts on the basis of two climatic features like hot and cold. Types are continental cold (CTc), continental hot (CTh), maritime cold (MTc) and maritime hot (MTh) air mass.

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
