input: Please answer the following: Given the following passage "There has, however, been interest among railroad operators in returning to DC use at higher voltages than previously used. At the same voltage, DC often has less loss than AC, and for this reason high-voltage direct current is already used on some bulk power transmission lines. DC avoids the electromagnetic radiation inherent with AC, and on a railway this also reduces interference with signalling and communications and mitigates hypothetical EMF risks. DC also avoids the power factor problems of AC. Of particular interest to railroading is that DC can supply constant power with a single ungrounded wire. Constant power with AC requires three-phase transmission with at least two ungrounded wires. Another important consideration is that mains-frequency 3-phase AC must be carefully planned to avoid unbalanced phase loads. Parts of the system are supplied from different phases on the assumption that the total loads of the 3 phases will even out. At the phase break points between regions supplied from different phases, long insulated supply breaks are required to avoid them being shorted by rolling stock using more than one pantograph at a time. A few railroads have tried 3-phase but its substantial complexity has made single-phase standard practice despite the interruption in power flow that occurs twice every cycle. An experimental 6 kV DC railway was built in the Soviet Union.", answer the following question. Note that the answer is present within the text. Question: Can supply constant power without having to use multiple ungrounded wires?

input: Please answer the following: Given the following passage "Like most Germanic languages, Dutch forms noun compounds, where the first noun modifies the category given by the second (hondenhok = doghouse). Unlike English, where newer compounds or combinations of longer nouns are often written in open form with separating spaces, Dutch (like the other Germanic languages) either uses the closed form without spaces (boomhuis = tree house) or inserts a hyphen (VVD-coryfee = outstanding member of the VVD, a political party). Like German, Dutch allows arbitrarily long compounds, but the longer they get, the less frequent they tend to be.", answer the following question. Note that the answer is present within the text. Question: What is the difference in spacing between dutch and english?
++++++++++
output: separating spaces

input: Please answer the following: Given the following passage "In Montevideo, as throughout the Rio de Plata region, the most popular forms of music are tango, milonga and vals criollo. Many notable songs originated in Montevideo including "El Tango supremo", La Cumparsita", La Milonga", "La Punalada" and "Desde el Alma", composed by notable Montevideo musicians such as Gerardo Matos Rodriguez, Pintin Castellanos and Rosita Melo. Tango is deeply ingrained in the cultural life of the city and is the theme for many of the bars and restaurants in the city. Fun Fun' Bar, established in 1935, is one of the most important places for tango in Uruguay as is El Farolito, located in the old part of the city and Joventango, Cafe Las Musas, Garufa and Vieja Viola. The city is also home to the Montevideo Jazz Festival and has the Bancaria Jazz Club bar catering for jazz enthusiasts.", answer the following question. Note that the answer is present within the text. Question: Which of the following is not a popular form of music in Montevideo: tango, milonga, or Uruguay?
++++++++++
output: Uruguay

input: Please answer the following: Given the following passage "Media Transfer Protocol (MTP) was designed by Microsoft to give higher-level access to a device's filesystem than USB mass storage, at the level of files rather than disk blocks. It also has optional DRM features. MTP was designed for use with portable media players, but it has since been adopted as the primary storage access protocol of the Android operating system from the version 4.1 Jelly Bean as well as Windows Phone 8 (Windows Phone 7 devices had used the Zune protocol which was an evolution of MTP). The primary reason for this is that MTP does not require exclusive access to the storage device the way UMS does, alleviating potential problems should an Android program request the storage while it is attached to a computer. The main drawback is that MTP is not as well supported outside of Windows operating systems.", answer the following question. Note that the answer is present within the text. Question: What microsoft product is MTP used for?

Windows Phone 8
