Why was the federal government granted the ability to maintain an army during peacetime by the constitution?

The clauses of the Constitution, which give Congress authority to raise and support armies, and so forth, were not inserted to endow the national government rather than the States with the power to do these things but to designate the department of the Federal Government, which would exercise the powers. As we have noted above, the English king was endowed with the power not only to initiate war but the power to raise and maintain armies and navies.1637 Aware historically that these powers had been used to the detriment of the liberties and well-being of Englishmen and aware that in the English Declaration of Rights of 1688 it was insisted that standing armies could not be maintained without the consent of Parliament, the Framers vested these basic powers in Congress.

when studying cause and effect, historians usually group the causes into different categories. for example, cultural causes reflect how a society’s literature and art convey the way the society saw itself in relation to the rest of the world. another resource that historians use to understand society is pop culture, which tells them the trends and ideas that are preferred by the common people. when studying cause and effect, it’s important to remember multiple causation, or the idea that an effect could have several causes and vice versa.  

the correct option is “cultural causes” since art and literature are related to the culture of a place. culture is determined by literature, art, music.

the correct option is “pop culture” since it reflects the likes and ideas of common people whereas the rest of the options do not focus on common people.  

the correct option is “multiple causation” since it refers to the idea that events are caused by multiple reasons, not just a single one.
