Problem: Super Nintendo Entertainment System:

While Nintendo never released an adapter for playing NES games on the SNES (though the instructions included a way to connect both consoles to the same TV by either daisy chaining the RF switches or using AV outputs for one or both systems), the Super Game Boy adapter cartridge allows games designed for Nintendo's portable Game Boy system to be played on the SNES. The Super Game Boy touted several feature enhancements over the Game Boy, including palette substitution, custom screen borders, and (for specially enhanced games) access to the SNES console. Japan also saw the release of the Super Game Boy 2, which added a communication port to enable a second Game Boy to connect for multiplayer games.

What improvements did the Super Game Boy have over the Game Boy?
---
A: palette substitution, custom screen borders, and (for specially enhanced games) access to the SNES console

Problem: The phase of reflection of electromagnetic waves depends on the polarization of the incident wave. Given the larger refractive index of the ground (typically n=2) compared to air (n=1), the phase of horizontally polarized radiation is reversed upon reflection (a phase shift of radians or 180). On the other hand, the vertical component of the wave's electric field is reflected at grazing angles of incidence approximately in phase. These phase shifts apply as well to a ground modelled as a good electrical conductor.
What is the refractive index of air?

Answer: n=1

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Near-infrared is the region closest in wavelength to the radiation detectable by the human eye, mid- and far-infrared are progressively further from the visible spectrum. Other definitions follow different physical mechanisms (emission peaks, vs. bands, water absorption) and the newest follow technical reasons (the common silicon detectors are sensitive to about 1,050 nm, while InGaAs's sensitivity starts around 950 nm and ends between 1,700 and 2,600 nm, depending on the specific configuration). Unfortunately, international standards for these specifications are not currently available.
What InGaAs is progressively further from the visible spectrum for the human eye?
A: unanswerable

Context and question: In orthography and typography, letter case (or just case) is the distinction between the letters that are in larger upper case (also capital letters, capitals, caps, large letters, or more formally majuscule, see Terminology) and smaller lower case (also small letters, or more formally minuscule, see Terminology) in the written representation of certain languages. Here is a comparison of the upper and lower case versions of each letter included in the English alphabet (the exact representation will vary according to the font used):
Capital letters refer to which case of letter?
Answer: larger upper

Question: In March 2005, the Security Council formally referred the situation in Darfur to the Prosecutor of the International Criminal Court, taking into account the Commission report but without mentioning any specific crimes. Two permanent members of the Security Council, the United States and China, abstained from the vote on the referral resolution. As of his fourth report to the Security Council, the Prosecutor has found "reasonable grounds to believe that the individuals identified [in the UN Security Council Resolution 1593] have committed crimes against humanity and war crimes," but did not find sufficient evidence to prosecute for genocide.
Is there an answer to this question: To whom did the Security Council officially refer the situation in China?

Answer: unanswerable

Question: During the Cantonal Revolution of 1873, a cantonalist uprising that took place during the First Spanish Republic, the city was consolidated with most of the nearby cities in the Federal Canton of Valencia (proclaimed on 19 July and dissolved on 7 August). It did not have the revolutionary fervor of the movement in cities like Alcoy, as it was initiated by the bourgeoisie, but the Madrid government sent General Martinez-Campos to stifle the rebellion by force of arms and subjected Valencia to an intense bombardment. The city surrendered on 7 August; Alfonso XII was proclaimed king on 29 December 1874, and arrived in Valencia on 11 January 1875 on his way to Madrid, marking the end of the first republic. Despite the Bourbon restoration, the roughly even balance between conservatives and liberals in the government was sustained in Valencia until the granting of universal male suffrage in 1890, after which the Republicans, led by Vicente Blasco Ibanez, gained considerably more of the popular vote.
Is there an answer to this question: Who was sent to stop Valencia's uprising?

Answer:
General Martinez-Campos
