Answer:
This article outlines some general aspects of the Magan and Dilmun trade and goes on to examine the Umm an-Nar pottery discovered in the tombs of the Early Dilmun burial mounds of Bahrain. These ceramics are of particular interest because they indirectly testify to Dilmun’s contact with Magan in the late third millennium. In this article, thirty vessels of seven morphological types are singled out. By comparison with the material published from the Oman peninsula the Bahrain collection is tentatively dated to c.2250–2000 BC. The location of the Umm an-Nar pottery within the distribution of burial mounds reveals that its import was strongly associated with the scattered mounds of Early Type. It is demonstrated that the frequency of Umm an-Nar pottery declined just as the ten compact cemeteries emerged c.2050 BC. The observed patterns are seen as a response to the decline of Magan and the rise of Dilmun.
According to the doctrine of separation of powers, the U.S. Constitution distributed the power of the federal government among these three branches, and built a system of checks and balances to ensure that no one branch could become too powerful.
Answer:
Megaliths were large stones thought to be used to observe the sky by ancient astronomers.
Explanation:
We can easily eliminate the first two options. They are indeed instruments used to observe astronomical movements, bodies, etc. However, they are simply not stones, so they are not related to the question.
We are left with megaliths and gastroliths, both words ending with the suffix -lith, which means they are both related to stones. "Gastro" refers to something related to the stomach, which is precisely the case here. A gastrolith is a stone found within the stomach of some animals. Finally, we are left with megaliths, large stones used to build monuments in ancient times which were likely used as very rudimentary astronomical observatories.
Other checks and balances include:. Executive over the judicial branch. The president appoints all federal judges. legislative branch must approve appointments that the president makes; the Senate must approve treatjes that the president makes; and the legislative branch may investigate the executive branch.
