Problem: Neptune:

Neptune has a number of known trojan objects occupying both the Sun–Neptune L4 and L5 Lagrangian points—gravitationally stable regions leading and trailing Neptune in its orbit, respectively. Neptune trojans can be viewed as being in a 1:1 resonance with Neptune. Some Neptune trojans are remarkably stable in their orbits, and are likely to have formed alongside Neptune rather than being captured. The first and so far only object identified as associated with Neptune's trailing L5 Lagrangian point is 2008 LC18. Neptune also has a temporary quasi-satellite, (309239) 2007 RW10. The object has been a quasi-satellite of Neptune for about 12,500 years and it will remain in that dynamical state for another 12,500 years.

 What is the resonance of Jupiter trojans?

Problem: True aspirated voiced consonants, as opposed to murmured (breathy-voice) consonants such as the [bʱ], [dʱ], [ɡʱ] that are common in the languages of India, are extremely rare. They have been documented in Kelabit Taa, and the Kx'a languages. Reported aspirated voiced stops, affricates and clicks are [b͡pʰ, d͡tʰ, d͡tsʰ, d͡tʃʰ, ɡ͡kʰ, ɢ͡qʰ, ᶢʘʰ, ᶢǀʰ, ᶢǁʰ, ᶢǃʰ, ᶢǂʰ].
Indian languages commonly have murmured consonants instead of what?

Answer: True aspirated voiced consonants


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
A few days before the fall of the city, the National Government of China was relocated to the southwestern city Chungking (Chongqing) and resumed Chinese resistance. In 1940, a Japanese-collaborationist government known as the "Nanjing Regime" or "Reorganized National Government of China" led by Wang Jingwei was established in Nanjing as a rival to Chiang Kai-shek's government in Chongqing. In 1946, after the Surrender of Japan, the KMT relocated its central government back to Nanjing.
When was the National Government of China moved to Chungking?
A: A few days before the fall of the city


Context and question: The reemergence of Cubism coincided with the appearance from about 1917–24 of a coherent body of theoretical writing by Pierre Reverdy, Maurice Raynal and Daniel-Henry Kahnweiler and, among the artists, by Gris, Léger and Gleizes. The occasional return to classicism—figurative work either exclusively or alongside Cubist work—experienced by many artists during this period (called Neoclassicism) has been linked to the tendency to evade the realities of the war and also to the cultural dominance of a classical or Latin image of France during and immediately following the war. Cubism after 1918 can be seen as part of a wide ideological shift towards conservatism in both French society and culture. Yet, Cubism itself remained evolutionary both within the oeuvre of individual artists, such as Gris and Metzinger, and across the work of artists as different from each other as Braque, Léger and Gleizes. Cubism as a publicly debated movement became relatively unified and open to definition. Its theoretical purity made it a gauge against which such diverse tendencies as Realism or Naturalism, Dada, Surrealism and abstraction could be compared.
What did not remain evolutionary?
Answer: unanswerable

A new style of wafers composed of gallium-nitride-on-silicon (GaN-on-Si) is being used to produce white LEDs using 200-mm silicon wafers. This avoids the typical costly sapphire substrate in relatively small 100- or 150-mm wafer sizes. The sapphire apparatus must be coupled with a mirror-like collector to reflect light that would otherwise be wasted. It is predicted that by 2020, 40% of all GaN LEDs will be made with GaN-on-Si. Manufacturing large sapphire material is difficult, while large silicon material is cheaper and more abundant. LED companies shifting from using sapphire to silicon should be a minimal investment.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What needs to not be used to reflect light that would otherwise be wasted?
Ah, so..
