d. eurasia.

Pangaea

Explanation:

The correct answer is C. The theory of plate tectonics suggests that about 200 million years ago, all of Earth's land was confined to a single continent called Pangaea.

Explanation:

Pangaea is the supercontinent that existed during the Mesozoic period before continental drift divided it into today's continents. Alfred Wegener postulated in 1915 the existence of such a "continent" in his theory of continental drift, and in the ensuing debate it was named Pangaea.

Pangaea was formed some 300 million years ago by coalescing the former supercontinent Gondwana (comprising present South America, Africa, Antarctica, Australia, Madagascar, Arabian Peninsula and India) and Laurasia (comprising North America, Europe and Siberia).  

Gondwana and Laurasia began to slide apart again during the Triassic (about 200 million years ago) and the cracking continued then until today's continents had formed under chalk (about 100 million years ago).

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
