Question: Neolithic peoples in the Levant, Anatolia, Syria, northern Mesopotamia and Central Asia were also accomplished builders, utilizing mud-brick to construct houses and villages. At Catal hoyuk, houses were plastered and painted with elaborate scenes of humans and animals. In Europe, long houses built from wattle and daub were constructed. Elaborate tombs were built for the dead. These tombs are particularly numerous in Ireland, where there are many thousand still in existence. Neolithic people in the British Isles built long barrows and chamber tombs for their dead and causewayed camps, henges, flint mines and cursus monuments. It was also important to figure out ways of preserving food for future months, such as fashioning relatively airtight containers, and using substances like salt as preservatives.

Question: Since the 19th century, many if not all presidents were assisted by a central figure or "gatekeeper", sometimes described as the President's Private Secretary, sometimes with no official title at all. Eisenhower formalized this role, introducing the office of White House Chief of Staff an idea he borrowed from the United States Army. Every president after Lyndon Johnson has also appointed staff to this position. Initially, Gerald Ford and Jimmy Carter tried to operate without a chief of staff, but each eventually appointed one.
Is there an answer to this question: Who was the last president not to appoint a Chief of Staff?

Answer: Lyndon Johnson

Question: Historians have divided the history of Cubism into phases. In one scheme, the first phase of Cubism, known as Analytic Cubism, a phrase coined by Juan Gris a posteriori, was both radical and influential as a short but highly significant art movement between 1910 and 1912 in France. A second phase, Synthetic Cubism, remained vital until around 1919, when the Surrealist movement gained popularity. English art historian Douglas Cooper proposed another scheme, describing three phases of Cubism in his book, The Cubist Epoch. According to Cooper there was "Early Cubism", (from 1906 to 1908) when the movement was initially developed in the studios of Picasso and Braque; the second phase being called "High Cubism", (from 1909 to 1914) during which time Juan Gris emerged as an important exponent (after 1911); and finally Cooper referred to "Late Cubism" (from 1914 to 1921) as the last phase of Cubism as a radical avant-garde movement. Douglas Cooper's restrictive use of these terms to distinguish the work of Braque, Picasso, Gris (from 1911) and Leger (to a lesser extent) implied an intentional value judgement.

Question: One may claim that the judiciary has historically been the weakest of the three branches. In fact, its power to exercise judicial reviewits sole meaningful check on the other two branchesis not explicitly granted by the U.S Constitution. The U.S. Supreme Court exercised its power to strike down congressional acts as unconstitutional only twice prior to the Civil War: in Marbury v. Madison (1803) and Dred Scott v. Sandford (1857). The Supreme Court has since then made more extensive use of judicial review.
Is there an answer to this question: Before the Civil War, the Marbury had exercised its power to strike down what type of acts only twice?
