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.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When did South Africa end occupation of Namibia?
Ah, so.. 1988

Whitehall's disquiet at the failures of the RAF led to the replacement of Dowding (who was already due for retirement) with Sholto Douglas on 25 November. Douglas set about introducing more squadrons and dispersing the few GL sets to create a carpet effect in the southern counties. Still, in February 1941, there remained only seven squadrons with 87 pilots, under half the required strength. The GL carpet was supported by six GCI sets controlling radar-equipped night-fighters. By the height of the Blitz, they were becoming more successful. The number of contacts and combats rose in 1941, from 44 and two in 48 sorties in January 1941, to 204 and 74 in May (643 sorties). But even in May, 67% of the sorties were visual cat's-eye missions. Curiously, while 43% of the contacts in May 1941 were by visual sightings, they accounted for 61% of the combats. Yet when compared with Luftwaffe daylight operations, there was a sharp decline in German losses to 1%. If a vigilant bomber crew could spot the fighter first, they had a decent chance at evading it.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did a bomber crew need to do for a good chance at evasion?
Ah, so.. spot the fighter first

From roughly 115 to 60 BC, Han forces fought the Xiongnu over control of the oasis city-states in the Tarim Basin. Han was eventually victorious and established the Protectorate of the Western Regions in 60 BC, which dealt with the region's defense and foreign affairs. The Han also expanded southward. The naval conquest of Nanyue in 111 BC expanded the Han realm into what are now modern Guangdong, Guangxi, and northern Vietnam. Yunnan was brought into the Han realm with the conquest of the Dian Kingdom in 109 BC, followed by parts of the Korean Peninsula with the colonial establishments of Xuantu Commandery and Lelang Commandery in 108 BC. In China's first known nationwide census taken in 2 AD, the population was registered as having 57,671,400 individuals in 12,366,470 households.
