What is the closest explanation of gilgamesh's exclamation in book xi: "what shall i do, where shall i go now? death has caught me, it lurks in my bedroom, and everywhere i look, everywhere i turn, there is only death."

   Gilgamesh realizes and accepts that he is mortal

Explanation:  The Gilgamesh Epic is the oldest written epic, considered by some to be, to some extent, not entirely, related to the historical Gilgamesh that ruled during the Sumerian civilization. Gilgamesh in pursuit of immortality goes to the old and wise Utnapishtim, who survived the great flood and became immortal. Utnapishtim seems to be the Noah character in the Bible. After all these questions about immortality, Gilgamesh realizes that he must rule as a just and wise king, but that he will not attain immortality.

the united states constitution is the supreme law of the united states. the constitution, originally comprising seven articles, delineates the national frame of government. its first three articles embody the doctrine of the separation of powers, whereby the federal government is divided into three branches: the legislative, consisting of the bicameral congress; the executive, consisting of the president; and the judicial, consisting of the supreme court and other federal courts. articles four, five and six embody concepts of federalism, describing the rights and responsibilities of state governments, the states in relationship to the federal government, and the shared process of constitutional amendment. article seven establishes the procedure subsequently used by the thirteen states to ratify it. it is regarded as the oldest written and codified national constitution in force.
