Input: Article: By the late 1990s, blue LEDs became widely available. They have an active region consisting of one or more InGaN quantum wells sandwiched between thicker layers of GaN, called cladding layers. By varying the relative In/Ga fraction in the InGaN quantum wells, the light emission can in theory be varied from violet to amber. Aluminium gallium nitride (AlGaN) of varying Al/Ga fraction can be used to manufacture the cladding and quantum well layers for ultraviolet LEDs, but these devices have not yet reached the level of efficiency and technological maturity of InGaN/GaN blue/green devices. If un-alloyed GaN is used in this case to form the active quantum well layers, the device will emit near-ultraviolet light with a peak wavelength centred around 365 nm. Green LEDs manufactured from the InGaN/GaN system are far more efficient and brighter than green LEDs produced with non-nitride material systems, but practical devices still exhibit efficiency too low for high-brightness applications.[citation needed]

Now answer this question: What does AlGaN stand for?

Output: Aluminium gallium nitride

Input: Article: According to Y chromosome studies by Sanchez et al. (2005), Cruciani et al. (2004, 2007), the Somalis are paternally closely related to other Afro-Asiatic-speaking groups in Northeast Africa. Besides comprising the majority of the Y-DNA in Somalis, the E1b1b1a (formerly E3b1a) haplogroup also makes up a significant proportion of the paternal DNA of Ethiopians, Sudanese, Egyptians, Berbers, North African Arabs, as well as many Mediterranean populations. Sanchez et al. (2005) observed the M78 subclade of E1b1b in about 77% of their Somali male samples. According to Cruciani et al. (2007), the presence of this subhaplogroup in the Horn region may represent the traces of an ancient migration from Egypt/Libya. After haplogroup E1b1b, the second most frequently occurring Y-DNA haplogroup among Somalis is the West Asian haplogroup T (M70). It is observed in slightly more than 10% of Somali males. Haplogroup T, like haplogroup E1b1b, is also typically found among populations of Northeast Africa, North Africa, the Near East and the Mediterranean.

Now answer this question: What language group speakers are ethnic Somalis closely related to?

Output: Afro-Asiatic

Input: Article: Twilight Princess received the awards for Best Artistic Design, Best Original Score, and Best Use of Sound from IGN for its GameCube version. Both IGN and Nintendo Power gave Twilight Princess the awards for Best Graphics and Best Story. Twilight Princess received Game of the Year awards from GameTrailers, 1UP.com, Electronic Gaming Monthly, Game Informer, Games Radar, GameSpy, Spacey Awards, X-Play and Nintendo Power. It was also given awards for Best Adventure Game from the Game Critics Awards, X-Play, IGN, GameTrailers, 1UP.com, and Nintendo Power. The game was considered the Best Console Game by the Game Critics Awards and GameSpy. The game placed 16th in Official Nintendo Magazine's list of the 100 Greatest Nintendo Games of All Time. IGN ranked the game as the 4th-best Wii game. Nintendo Power ranked the game as the third-best game to be released on a Nintendo system in the 2000s decade.

Now answer this question: What place did IGN give the game on the Wii console?

Output:
4th
