In addition to the archaeological legacy discussed above, there remains from this period the earliest literary record of Indian culture, the Vedas. Composed in archaic, or Vedic, Sanskrit, generally dated between 1500 and 800 BCE, and transmitted orally, the Vedas comprise four major texts—the Rig-, the Sama-, the Yajur-, and the Atharvaveda. Of these, the Rigveda is believed to be the earliest. The texts consist of hymns, charms, spells, and ritual observations current among the Indo-European-speaking people known as Aryans (from Sanskrit arya, “noble”), who presumably entered India from the Iranian regions.
As nomadic group of people which belonged to the region around the Capsian Sea, The Huns were responsibles for the Great Migration<em>.</em>
With brutal invasions of the regions sorrounding the Roman Empire, this tribe encouraged such migration, also known as the "Wandering of the Nations", which began between 300 and 700 CE, and was formed by the Alans, Goths, and Vandals among others.
They moved fast and were successful at battle. In 370 CE, they defeated and conquered the Alans, by 376 CE had pushed the Goths into Roman territory, and by 379 CE had pushed the people under the leadership of Athanaric into the Caucalands. These attacks produced a <em>domino effect </em>since many tribes, in their escape, sought refuge in Roman territory.
Such migration altered the conditions of roman society and eventually, after many insurrections and raids from these tribes, the Western Empire was weakened and collapsed.
C) is the correct answer. <u><em>The Constitution makes the President the chief administrator of the Federal Government.
</em></u>
<em>The United States Constitution say in Article. II. - The Executive Branch Section 1 - The President</em> that:
<em>The Executive Power shall be vested in a President of the United States of America. He shall hold his Office during the Term of four Years…
</em>
The President is the Chief of state, Chief executive, Chief administrator, Chief diplomat, Commander in chief, Chief legislator, Chief of party, Chief citizen
.
As chief administrator, the President is in charge of the executive branch of the federal government, so he is in the top of the bureaucracy.
