Problem: IPod:

Many accessories have been made for the iPod line. A large number are made by third party companies, although many, such as the iPod Hi-Fi, are made by Apple. Some accessories add extra features that other music players have, such as sound recorders, FM radio tuners, wired remote controls, and audio/visual cables for TV connections. Other accessories offer unique features like the Nike+iPod pedometer and the iPod Camera Connector. Other notable accessories include external speakers, wireless remote controls, protective case, screen films, and wireless earphones. Among the first accessory manufacturers were Griffin Technology, Belkin, JBL, Bose, Monster Cable, and SendStation.

Which company manufactures the iPod Hi-Fi accessory?

A: Apple

Problem: High-voltage AC overhead systems are not only for standard gauge national networks. The meter gauge Rhaetian Railway (RhB) and the neighbouring Matterhorn Gotthard Bahn (MGB) operate on 11 kV at 16.7 Hz frequency. Practice has proven that both Swiss and German 15 kV trains can operate under these lower voltages. The RhB started trials of the 11 kV system in 1913 on the Engadin line (St. Moritz-Scuol/Tarasp). The MGB constituents Furka-Oberalp-Bahn (FO) and Brig-Visp-Zermatt Bahn (BVZ) introduced their electric services in 1941 and 1929 respectively, adopting the already proven RhB system.
Which European trains can operate under high voltages?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Public schools in Raleigh are operated by the Wake County Public School System. Observers have praised the Wake County Public School System for its innovative efforts to maintain a socially, economically and racial balanced system by using income as a prime factor in assigning students to schools. Raleigh is home to three magnet high schools and three high schools offering the International Baccalaureate program. There are four early college high schools in Raleigh. Raleigh also has two alternative high schools.
What is the private school name?
A: unanswerable

Context and question: The central oscillator generates a self-sustaining rhythm and is driven by two interacting feedback loops that are active at different times of day. The morning loop consists of CCA1 (Circadian and Clock-Associated 1) and LHY (Late Elongated Hypocotyl), which encode closely related MYB transcription factors that regulate circadian rhythms in Arabidopsis, as well as PRR 7 and 9 (Pseudo-Response Regulators.) The evening loop consists of GI (Gigantea) and ELF4, both involved in regulation of flowering time genes. When CCA1 and LHY are overexpressed (under constant light or dark conditions), plants become arrhythmic, and mRNA signals reduce, contributing to a negative feedback loop. Gene expression of CCA1 and LHY oscillates and peaks in the early morning, whereas TOC1 gene expression oscillates and peaks in the early evening. While it was previously hypothesised that these three genes model a negative feedback loop in which over-expressed CCA1 and LHY repress TOC1 and over-expressed TOC1 is a positive regulator of CCA1 and LHY, it was shown in 2012 by Andrew Millar and others that TOC1 in fact serves as a repressor not only of CCA1, LHY, and PRR7 and 9 in the morning loop but also of GI and ELF4 in the evening loop. This finding and further computational modeling of TOC1 gene functions and interactions suggest a reframing of the plant circadian clock as a triple negative-component repressilator model rather than the positive/negative-element feedback loop characterizing the clock in mammals.
What is driven by single feedback loop?
Answer: unanswerable

Question: Perhaps the greatest question regarding the future development of transnational policing is: in whose interest is it? At a more practical level, the question translates into one about how to make transnational policing institutions democratically accountable (Sheptycki, 2004). For example, according to the Global Accountability Report for 2007 (Lloyd, et al. 2007) Interpol had the lowest scores in its category (IGOs), coming in tenth with a score of 22% on overall accountability capabilities (p. 19). As this report points out, and the existing academic literature on transnational policing seems to confirm, this is a secretive area and one not open to civil society involvement.
Is there an answer to this question: Who wrote the Global Accountability Report for 2007?

Answer: Lloyd, et al.

Problem: Dutch language:

Dutch belongs to its own West Germanic sub-group, West Low Franconian, paired with its sister language Limburgish, or East Low Franconian. Closest relative is the mutual intelligible daughter language Afrikaans. Other West Germanic languages related to Dutch are German, English and the Frisian languages, and the non standardised languages Low German and Yiddish. Dutch stands out in combining a small degree of Ingvaeonic characteristics (occurring consistently in English and Frisian and reduced in intensity from 'west to east' over the continental West Germanic plane) with mostly Istvaeonic characteristics, of which some of them are also incorporated in German. Unlike German, Dutch (apart from Limburgish) has not been influenced at all by the 'south to north' movement of the High German sound shift, and had some changes of its own. The cumulation of these changes resulted over time in separate, but related standard languages with various degrees of similarities and differences between them. For a comparison between the West Germanic languages, see the sections Morphology, Grammar and Vocabulary.

As opposed to Dutch, what language was influenced by the High German sound shift?

A:
German
