Problem: In response to the 1966 ruling by the International Court of Justice, South-West Africa People's Organisation (SWAPO) military wing, People's Liberation Army of Namibia, a guerrilla group began their armed struggle for independence, but it was not until 1988 that South Africa agreed to end its occupation of Namibia, in accordance with a UN peace plan for the entire region. During the South African occupation of Namibia, white commercial farmers, most of whom came as settlers from South Africa and represented 0.2% of the national population, owned 74% of the arable land. Outside the central-southern area of Namibia (known as the "Police Zone" since the German era and which contained the main towns, industries, mines and best arable land), the country was divided into "homelands", the version of South African bantustan applied to Namibia, although only a few were actually established because indigenous Namibians often did not cooperate.
Why did South Africa end occupation in Namibia?

Problem: The first lighting used on an airport was during the latter part of the 1920s; in the 1930s approach lighting came into use. These indicated the proper direction and angle of descent. The colours and flash intervals of these lights became standardized under the International Civil Aviation Organization (ICAO). In the 1940s, the slope-line approach system was introduced. This consisted of two rows of lights that formed a funnel indicating an aircraft's position on the glideslope. Additional lights indicated incorrect altitude and direction.
What did the flash interval system consist of?

Answer: unanswerable


Problem: In Australia, a technical issue arose with the royal assent in both 1976 and 2001. In 1976, a bill originating in the House of Representatives was mistakenly submitted to the Governor-General and assented to. However, it was later discovered that it had not been passed by each house. The error arose because two bills of the same title had originated from the house. The Governor-General revoked the first assent, before assenting to the bill which had actually passed. The same procedure was followed to correct a similar error which arose in 2001.
The bill from the Australian House of Representatives was mistakenly sent and assented to by whom in 1976?

Governor-General
