Question: Polyols, compounds containing more than one alcohol functional group, generally interact with cupric salts. For example, copper salts are used to test for reducing sugars. Specifically, using Benedict's reagent and Fehling's solution the presence of the sugar is signaled by a color change from blue Cu(II) to reddish copper(I) oxide. Schweizer's reagent and related complexes with ethylenediamine and other amines dissolve cellulose. Amino acids form very stable chelate complexes with copper(II). Many wet-chemical tests for copper ions exist, one involving potassium ferrocyanide, which gives a brown precipitate with copper(II) salts.
Try to answer this question if possible: What does Schweizer's reagent dissolve?
Answer: cellulose
Question: Some countries have multiple "supreme courts" whose respective jurisdictions have different geographical extents, or which are restricted to particular areas of law. In particular, countries with a federal system of government typically[citation needed] have both a federal supreme court (such as the Supreme Court of the United States), and supreme courts for each member state (such as the Supreme Court of Nevada), with the former having jurisdiction over the latter only to the extent that the federal constitution extends federal law over state law. Jurisdictions with a civil law system often have a hierarchy of administrative courts separate from the ordinary courts, headed by a supreme administrative court as it the case in the Netherlands. A number of jurisdictions also maintain a separate constitutional court (first developed in the Czechoslovak Constitution of 1920), such as Austria, France, Germany, Luxemburg, Portugal, Spain and South Africa.
Try to answer this question if possible: What is an example of the highest court in a federal system of government?
Answer: the Supreme Court of the United States
Question: International reactions to Gaddafi's death were divided. U.S. President Barack Obama stated that it meant that "the shadow of tyranny over Libya has been lifted," while UK Prime Minister David Cameron stated that he was "proud" of his country's role in overthrowing "this brutal dictator". Contrastingly, former Cuban President Fidel Castro commented that in defying the rebels, Gaddafi would "enter history as one of the great figures of the Arab nations", while Venezuelan President Hugo Chavez described him as "a great fighter, a revolutionary and a martyr." Nelson Mandela expressed sadness at the news, praising Gaddafi for his anti-apartheid stance, remarking that he backed the African National Congress during "the darkest moments of our struggle". Gaddafi was mourned by many as a hero across Sub-Saharan Africa, for instance, a vigil was held by Muslims in Sierra Leone. The Daily Times of Nigeria stated that while undeniably a dictator, Gaddafi was the most benevolent in a region that only knew dictatorship, and that he was "a great man that looked out for his people and made them the envy of all of Africa." The Nigerian newspaper Leadership reported that while many Libyans and Africans would mourn Gaddafi, this would be ignored by western media and that as such it would take 50 years before historians decided whether he was "martyr or villain."
Try to answer this question if possible: Who expressed pride at overthrowing Gaddafi's government?
Answer: David Cameron
Question: The United States had multiple rocket programs divided among the different branches of the American armed services, which meant that each force developed its own ICBM program. The Air Force initiated ICBM research in 1945 with the MX-774. However, its funding was cancelled and only three partially successful launches were conducted in 1947. In 1950, von Braun began testing the Air Force PGM-11 Redstone rocket family at Cape Canaveral. In 1951, the Air Force began a new ICBM program called MX-1593, and by 1955 this program was receiving top-priority funding. The MX-1593 program evolved to become the Atlas-A, with its maiden launch occurring June 11, 1957, becoming the first successful American ICBM. Its upgraded version, the Atlas-D rocket, would later serve as an operational nuclear ICBM and as the orbital launch vehicle for Project Mercury and the remote-controlled Agena Target Vehicle used in Project Gemini.
Try to answer this question if possible: What type of rocket was first researched by the Air Force?
Answer:
MX-774
