Problem: Please answer a question about the following article about American Idol:
Both finalists found success after the show, but Aiken out-performed Studdard's coronation song "Flying Without Wings" with his single release from the show "This Is the Night", as well as in their subsequent album releases. The fourth-place finisher Josh Gracin also enjoyed some success as a country singer.
What was the name of Studdard's coronation song?
A: Flying Without Wings
Problem: Please answer a question about the following article about John Kerry:
In 1970, Kerry had considered running for Congress in the Democratic primary against hawkish Democrat Philip J. Philbin of Massachusetts's 3rd congressional district, but deferred in favour of Robert Drinan, a Jesuit priest and anti-war activist, who went on to defeat Philbin. In February 1972, Kerry's wife bought a house in Worcester, with Kerry intending to run against the 4th district's ageing thirteen-term incumbent Democrat, Harold Donohue. The couple never moved in. After Republican Congressman F. Bradford Morse of the neighbouring 5th district announced his retirement and then resignation to become Under-Secretary-General for Political and General Assembly Affairs at the United Nations. The couple instead rented an apartment in Lowell, so that Kerry could run to succeed him.
Why did Morse retire?
A: to become Under-Secretary-General for Political and General Assembly Affairs at the United Nations
Problem: Please answer a question about the following article about Antenna (radio):
Consider a half-wave dipole designed to work with signals 1 m wavelength, meaning the antenna would be approximately 50 cm across. If the element has a length-to-diameter ratio of 1000, it will have an inherent resistance of about 63 ohms. Using the appropriate transmission wire or balun, we match that resistance to ensure minimum signal loss. Feeding that antenna with a current of 1 ampere will require 63 volts of RF, and the antenna will radiate 63 watts (ignoring losses) of radio frequency power. Now consider the case when the antenna is fed a signal with a wavelength of 1.25 m; in this case the reflected current would arrive at the feed out-of-phase with the signal, causing the net current to drop while the voltage remains the same. Electrically this appears to be a very high impedance. The antenna and transmission line no longer have the same impedance, and the signal will be reflected back into the antenna, reducing output. This could be addressed by changing the matching system between the antenna and transmission line, but that solution only works well at the new design frequency.
What effect occurs when the signal is reflected back into the antenna?
A: reducing output
Problem: Please answer a question about the following article about Neoclassical architecture:
Seen in its wider social context, Greek Revival architecture sounded a new note of sobriety and restraint in public buildings in Britain around 1800 as an assertion of nationalism attendant on the Act of Union, the Napoleonic Wars, and the clamour for political reform. It was to be William Wilkins's winning design for the public competition for Downing College, Cambridge that announced the Greek style was to be the dominant idiom in architecture. Wilkins and Robert Smirke went on to build some of the most important buildings of the era, including the Theatre Royal, Covent Garden (180809), the General Post Office (182429) and the British Museum (182348), Wilkins University College London (182630) and the National Gallery (183238). In Scotland, Thomas Hamilton (17841858), in collaboration with the artists Andrew Wilson (17801848) and Hugh William Williams (17731829) created monuments and buildings of international significance; the Burns Monument at Alloway (1818) and the (Royal) High School in Edinburgh (182329).
Whose winning design for public competition began the dominance of Greek style architecture?
A:
William Wilkins
