On April 12, 1980, a military coup led by Master Sergeant Samuel Doe of the Krahn ethnic group overthrew and killed President William R. Tolbert, Jr.. Doe and the other plotters later executed a majority of Tolbert's cabinet and other Americo-Liberian government officials and True Whig Party members. The coup leaders formed the People's Redemption Council (PRC) to govern the country. A strategic Cold War ally of the West, Doe received significant financial backing from the United States while critics condemned the PRC for corruption and political repression.
On what date was William R. Tolbert killed?
****
The answer: April 12, 1980

There have been instances where a country's government bans a movie, resulting in the spread of copied videos and DVDs. Romanian-born documentary maker Ilinca Calugareanu wrote a New York Times article telling the story of Irina Margareta Nistor, a narrator for state TV under Nicolae Ceausescu's regime. A visitor from the west gave her bootlegged copies of American movies, which she dubbed for secret viewings through Romania. According to the article, she dubbed more than 3,000 movies and became the country's second-most famous voice after Ceausescu, even though no one knew her name until many years later.
Who did documentary maker Ilinca Calugareanu write an article for?
****
The answer: New York Times

Film speed is used in the exposure equations to find the appropriate exposure parameters. Four variables are available to the photographer to obtain the desired effect: lighting, film speed, f-number (aperture size), and shutter speed (exposure time). The equation may be expressed as ratios, or, by taking the logarithm (base 2) of both sides, by addition, using the APEX system, in which every increment of 1 is a doubling of exposure; this increment is commonly known as a "stop". The effective f-number is proportional to the ratio between the lens focal length and aperture diameter, the diameter itself being proportional to the square root of the aperture area. Thus, a lens set to f/1.4 allows twice as much light to strike the focal plane as a lens set to f/2. Therefore, each f-number factor of the square root of two (approximately 1.4) is also a stop, so lenses are typically marked in that progression: f/1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, etc.
What is the effective f-number proportional to?
****
The answer: the ratio between the lens focal length and aperture diameter
