As African states became independent in the 1960s, the Soviet Union offered many of their citizens the chance to study in Russia. Over a period of 40 years, about 400,000 African students from various countries moved to Russia to pursue higher studies, including many Black Africans. This extended beyond the Soviet Union to many countries of the Eastern bloc.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Why did students move to Russia?
Ah, so.. to pursue higher studies

The Nintendo Entertainment System (also abbreviated as NES) is an 8-bit home video game console that was developed and manufactured by Nintendo. It was initially released in Japan as the Family Computer (Japanese: ファミリーコンピュータ, Hepburn: Famirī Konpyūta?) (also known by the portmanteau abbreviation Famicom (ファミコン, Famikon?) and abbreviated as FC) on July 15, 1983, and was later released in North America during 1985, in Europe during 1986, and Australia in 1987. In South Korea, it was known as the Hyundai Comboy (현대 컴보이 Hyeondae Keomboi) and was distributed by SK Hynix which then was known as Hyundai Electronics. It was succeeded by the Super Nintendo Entertainment System.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is the abbreviation of Nintendo Entertainment System?
Ah, so.. NES

The maximum energy is a function of dielectric volume, permittivity, and dielectric strength. Changing the plate area and the separation between the plates while maintaining the same volume causes no change of the maximum amount of energy that the capacitor can store, so long as the distance between plates remains much smaller than both the length and width of the plates. In addition, these equations assume that the electric field is entirely concentrated in the dielectric between the plates. In reality there are fringing fields outside the dielectric, for example between the sides of the capacitor plates, which will increase the effective capacitance of the capacitor. This is sometimes called parasitic capacitance. For some simple capacitor geometries this additional capacitance term can be calculated analytically. It becomes negligibly small when the ratios of plate width to separation and length to separation are large.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When the ratios of plate length and width to separation distance are small, what size is the parasitic capacitance?
Ah, so..
unanswerable
