You already arranged them in order–Xia is first, then Shang, then Zhou.
The Xia Dynasty is the first dynasty in the history of China.
The Shang Dynasty lasted from 1700 BCE to 1027 BCE.
Finally, the Zhou Dynasty lasted from 1046 BCE to 256 BCE.
hr2520 is the patient's act. there is required the secretary of health to summon a committee to develop a national strategic plan of prevention. this committee has forth provisions that make possible for the govern entities to acquire private health insurance services.
is easier to keep this hr2520 as federal, because that way the secretary of health has centralized power to deal with private insurance companies and the federas government has more ways and power to negotiate with them, than doing this process state by state in their specific terms.
the addition to geographic boundaries that might have kept the people of the huang river civilization from traveling to far distance region is that they had learned about the other river valley civilizations but feared contact would bring invasion.
hope this .
plz give me brainliest!
