question:
Which crest inspired the creation of another?, Context: Unveiled in 1888, Royal Arsenal's first crest featured three cannon viewed from above, pointing northwards, similar to the coat of arms of the Metropolitan Borough of Woolwich (nowadays transferred to the coat of arms of the Royal Borough of Greenwich). These can sometimes be mistaken for chimneys, but the presence of a carved lion's head and a cascabel on each are clear indicators that they are cannon. This was dropped after the move to Highbury in 1913, only to be reinstated in 1922, when the club adopted a crest featuring a single cannon, pointing eastwards, with the club's nickname, The Gunners, inscribed alongside it; this crest only lasted until 1925, when the cannon was reversed to point westward and its barrel slimmed down.
answer:
the coat of arms of the Metropolitan Borough of Woolwich


question:
Which of the following is NOT a goal of phorphor LED development: higher light output, optical losses, or higher operation temperatures?, Context: Among the challenges being faced to improve the efficiency of LED-based white light sources is the development of more efficient phosphors. As of 2010, the most efficient yellow phosphor is still the YAG phosphor, with less than 10% Stoke shift loss. Losses attributable to internal optical losses due to re-absorption in the LED chip and in the LED packaging itself account typically for another 10% to 30% of efficiency loss. Currently, in the area of phosphor LED development, much effort is being spent on optimizing these devices to higher light output and higher operation temperatures. For instance, the efficiency can be raised by adapting better package design or by using a more suitable type of phosphor. Conformal coating process is frequently used to address the issue of varying phosphor thickness.
answer:
optical losses


question:
Who caused the death of Ganondorf?, Context: Ganondorf then revives, and Midna teleports Link and Zelda outside the castle so she can hold him off with the Fused Shadows. However, as Hyrule Castle collapses, it is revealed that Ganondorf was victorious as he crushes Midna's helmet. Ganondorf engages Link on horseback, and, assisted by Zelda and the Light Spirits, Link eventually knocks Ganondorf off his horse and they duel on foot before Link strikes down Ganondorf and plunges the Master Sword into his chest. With Ganondorf dead, the Light Spirits not only bring Midna back to life, but restore her to her true form. After bidding farewell to Link and Zelda, Midna returns home before destroying the Mirror of Twilight with a tear to maintain balance between Hyrule and the Twilight Realm. Near the end, as Hyrule Castle is rebuilt, Link is shown leaving Ordon Village heading to parts unknown.
answer:

Link
