The reason why it takes a long time to ratify the Articles of Confederation is that U.S. just declared independent from Britain, in other words, they just passed the Declaration of Independence, and in order to keep a country on track, they need some sorts of form of government, and they don't want to repeating the history, or have another tyrant, or a king, to rule over them again, which is a part of reason why they declared independent (the actual reasons is the king taxes us for no reason and we can't participate in the government), so they need all of the 13 states to approve, or sign, the Articles of Confederation, majority of them signed it, some of them having issues about the rights in the Articles of Confederation, so someone, I forgot his name, promised to includes all of the rights into the Articles of Confederation, which they can't do it instantly, which later known as the Bill of Rights (the first 10 amendments), so it takes longer to get the whole Articles of Confederation to be approved, or ratified.
Hope this help, my English is not that well so please excuse for it.
I really think the answer is (C) Our solar system follows an orbit through the Milky Way Galaxy that takes hundreds of millions of years to complete because our sun and solar system move at about 500,000 miles an hour (800,000 km/hr) in this huge orbit. So in 90 seconds, for example, we all move some 12,500 miles (20,000 km) in orbit around the galaxy's center
One way in which federalism has evolved from the New Deal to what it has become today is that many of the government programs that were intended to "jumpstart" the economy during the Great Depression--such as the WPA--have shifted into programs like Medicare and Medicaid, which provide federal assistance to people on a regular basis.
