Input: Read this: On release, Twilight Princess was considered to be the greatest Zelda game ever made by many critics including writers for 1UP.com, Computer and Video Games, Electronic Gaming Monthly, Game Informer, GamesRadar, IGN and The Washington Post. Game Informer called it "so creative that it rivals the best that Hollywood has to offer". GamesRadar praised Twilight Princess as "a game that deserves nothing but the absolute highest recommendation". Cubed3 hailed Twilight Princess as "the single greatest videogame experience". Twilight Princess's graphics were praised for the art style and animation, although the game was designed for the GameCube, which is technically lacking compared to the next generation consoles. Both IGN and GameSpy pointed out the existence of blurry textures and low-resolution characters. Despite these complaints, Computer and Video Games felt the game's atmosphere was superior to that of any previous Zelda game, and regarded Twilight Princess's Hyrule as the best version ever created. PALGN praised the game's cinematics, noting that "the cutscenes are the best ever in Zelda games". Regarding the Wii version, GameSpot's Jeff Gerstmann said the Wii controls felt "tacked-on", although 1UP.com said the remote-swinging sword attacks were "the most impressive in the entire series". Gaming Nexus considered Twilight Princess's soundtrack to be the best of this generation, though IGN criticized its MIDI-formatted songs for lacking "the punch and crispness" of their orchestrated counterparts. Hyper's Javier Glickman commended the game for its "very long quests, superb Wii controls and being able to save anytime". However, he criticised it for "no voice acting, no orchestral score and slightly outdated graphics".

Input: Read this: About half of the population depends on agriculture (largely subsistence agriculture) for its livelihood, but Namibia must still import some of its food. Although per capita GDP is five times the per capita GDP of Africa's poorest countries, the majority of Namibia's people live in rural areas and exist on a subsistence way of life. Namibia has one of the highest rates of income inequality in the world, due in part to the fact that there is an urban economy and a more rural cash-less economy. The inequality figures thus take into account people who do not actually rely on the formal economy for their survival. Although arable land accounts for only 1% of Namibia, nearly half of the population is employed in agriculture.

Input: Read this: Most electrification systems use overhead wires, but third rail is an option up to about 1,200 V. Third rail systems exclusively use DC distribution. The use of AC is not feasible because the dimensions of a third rail are physically very large compared with the skin depth that the alternating current penetrates to (0.3 millimetres or 0.012 inches) in a steel rail). This effect makes the resistance per unit length unacceptably high compared with the use of DC. Third rail is more compact than overhead wires and can be used in smaller-diameter tunnels, an important factor for subway systems.
Question: What depth does the alternating current penetrate in a steel rail?

Output: skin depth
