[EX Q]: Providing 25% of Namibia's revenue, mining is the single most important contributor to the economy. Namibia is the fourth largest exporter of non-fuel minerals in Africa and the world's fourth largest producer of uranium. There has been significant investment in uranium mining and Namibia is set to become the largest exporter of uranium by 2015. Rich alluvial diamond deposits make Namibia a primary source for gem-quality diamonds. While Namibia is known predominantly for its gem diamond and uranium deposits, a number of other minerals are extracted industrially such as lead, tungsten, gold, tin, fluorspar, manganese, marble, copper and zinc. There are offshore gas deposits in the Atlantic Ocean that are planned to be extracted in the future. According to "The Diamond Investigation", a book about the global diamond market, from 1978, De Beers, the largest diamond company, bought most of the Namibian diamonds, and would continue to do so, because "whatever government eventually comes to power they will need this revenue to survive".
[EX A]: How much revenue does mining provide Namibia?

[EX Q]: The popular neighborhood known as the Tower District is centered around the historic Tower Theatre, which is included on the National List of Historic Places. The theater was built in 1939 and is at Olive and Wishon Avenues in the heart of the Tower District. (The name of the theater refers to a well-known landmark water tower, which is actually in another nearby area). The Tower District neighborhood is just north of downtown Fresno proper, and one-half mile south of Fresno City College. Although the neighborhood was known as a residential area prior, the early commercial establishments of the Tower District began with small shops and services that flocked to the area shortly after World War II. The character of small local businesses largely remains today. To some extent, the businesses of the Tower District were developed due to the proximity of the original Fresno Normal School, (later renamed California State University at Fresno). In 1916 the college moved to what is now the site of Fresno City College one-half mile north of the Tower District.
[EX A]: The Tower District is centered around which historic theatre?

[EX Q]: The Axis states which assisted Japan included the authoritarian government of Thailand in World War II, which quickly formed a temporary alliance with the Japanese in 1941, as the Japanese forces were already invading the peninsula of southern Thailand. The Phayap Army sent troops to invade and occupy northeastern Burma, which was former Thai territory that had been annexed by Britain much earlier. Also involved were the Japanese puppet states of Manchukuo and Mengjiang (consisting of most of Manchuria and parts of Inner Mongolia respectively), and the collaborationist Wang Jingwei regime (which controlled the coastal regions of China).
[EX A]:
What role did Thailand play in the war?
