Answer:
I can't answer 13, but 14 is silk, ancient China kept secret the way to make silk because (15) it gave them an advantage in trade (the silk road) because other countries would trade their goods for silk since china wouldn't tell them how to make it. Hope this helps!
The year is 570 CE, it shows how trade routes were really popular when Islam was spreading.
Islam appeared in the 7th century, and in the Muslim religious tradition, the rise of religion happened through Muhammad (better known in Portuguese as Muhammad). The great prophet of Islam was born in AD 570, and for much of his life he worked as a merchant.
Muhammad's life changed when he received a revelation from the angel Gabriel, in what became known in the Muslim religious tradition as the Night of Destiny. Muslims do not worship Muhammad, but they consider him to be the last in a series of prophets who brought the revelation of Allah's message.
The best answer choice would be A.
I sure don't have time to write an essay! But the first one sounds alright.
One of the early Chinese civilizations was located between the two main rivers, (google them for more details) Anyways, unlike most of China, the plain between the two rivers is fertile, allowing the people to grow rice and other foods. Along with that, I am certain that they had mountains and deserts to the west. If they could be used against natural disasters (I doubt they'd come in west) it'd be helpful! Good day
