Problem: Question: "The US Congress is composed of two branches, one composed of representatives and the other called?" Context: "Menzies ran strongly against Labor's plans to nationalise the Australian banking system and, following victory in the 1949 election, secured a double dissolution election for April 1951, after the Labor-controlled Senate refused to pass his banking legislation. The Liberal-Country Coalition was returned with control of the Senate. The Government was returned again in the 1954 election; the formation of the anti-Communist Democratic Labor Party (DLP) and the consequent split in the Australian Labor Party early in 1955 helped the Liberals to another victory in December 1955. John McEwen replaced Arthur Fadden as leader of the Country Party in March 1958 and the Menzies-McEwen Coalition was returned again at elections in November 1958 their third victory against Labor's H. V. Evatt. The Coalition was narrowly returned against Labor's Arthur Calwell in the December 1961 election, in the midst of a credit squeeze. Menzies stood for office for the last time in the November 1963 election, again defeating Calwell, with the Coalition winning back its losses in the House of Representatives. Menzies went on to resign from parliament on 26 January 1966." Answer:

A: Senate

Problem: Question: "Where was the attack?" Context: "The city and surrounding area suffered the bulk of the economic damage and largest loss of human life in the aftermath of the September 11, 2001 attacks when 10 of the 19 terrorists associated with Al-Qaeda piloted American Airlines Flight 11 into the North Tower of the World Trade Center and United Airlines Flight 175 into the South Tower of the World Trade Center, and later destroyed them, killing 2,192 civilians, 343 firefighters, and 71 law enforcement officers who were in the towers and in the surrounding area. The rebuilding of the area, has created a new One World Trade Center, and a 9/11 memorial and museum along with other new buildings and infrastructure. The World Trade Center PATH station, which opened on July 19, 1909 as the Hudson Terminal, was also destroyed in the attack. A temporary station was built and opened on November 23, 2003. A permanent station, the World Trade Center Transportation Hub, is currently under construction. The new One World Trade Center is the tallest skyscraper in the Western Hemisphere and the fourth-tallest building in the world by pinnacle height, with its spire reaching a symbolic 1,776 feet (541.3 m) in reference to the year of American independence." Answer:

A: World Trade Center

Answer:

A: two-thirds

Problem: Question: "The visuals are created through?" Context: "The structure of QD-LEDs used for the electrical-excitation scheme is similar to basic design of OLEDs. A layer of quantum dots is sandwiched between layers of electron-transporting and hole-transporting materials. An applied electric field causes electrons and holes to move into the quantum dot layer and recombine forming an exciton that excites a QD. This scheme is commonly studied for quantum dot display. The tunability of emission wavelengths and narrow bandwidth is also beneficial as excitation sources for fluorescence imaging. Fluorescence near-field scanning optical microscopy (NSOM) utilizing an integrated QD-LED has been demonstrated." Answer:

A:
imaging
