Q: 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: DC is less hazardous than AC because it generates less?
A: electromagnetic radiation

Q: Given the following passage "In October 1745, Ewald Georg von Kleist of Pomerania, Germany, found that charge could be stored by connecting a high-voltage electrostatic generator by a wire to a volume of water in a hand-held glass jar. Von Kleist's hand and the water acted as conductors, and the jar as a dielectric (although details of the mechanism were incorrectly identified at the time). Von Kleist found that touching the wire resulted in a powerful spark, much more painful than that obtained from an electrostatic machine. The following year, the Dutch physicist Pieter van Musschenbroek invented a similar capacitor, which was named the Leyden jar, after the University of Leiden where he worked. He also was impressed by the power of the shock he received, writing, "I would not take a second shock for the kingdom of France."", answer the following question. Note that the answer is present within the text. Question: Who do we likely have to thank for the initial discovery that led to modern-day capacitors?
A: Ewald Georg von Kleist

Q: Given the following passage "The era of planning in Himachal Pradesh started 1948 along with the rest of India. The first five-year plan allocated 52.7 million to Himachal. More than 50% of this expenditure was incurred on road construction since it was felt that without proper transport facilities, the process of planning and development could not be carried to the people, who mostly lived an isolated existence in far away areas. Himachal now ranks fourth in respect of per capita income among the states of the Indian Union.", answer the following question. Note that the answer is present within the text. Question: why road construction?
A: it was felt that without proper transport facilities, the process of planning and development could not be carried to the people

Q: Given the following passage "The Cubs had high expectations in 2002, but the squad played poorly. On July 5, 2002 the Cubs promoted assistant general manager and player personnel director Jim Hendry to the General Manager position. The club responded by hiring Dusty Baker and by making some major moves in '03. Most notably, they traded with the Pittsburgh Pirates for outfielder Kenny Lofton and third baseman Aramis Ramirez, and rode dominant pitching, led by Kerry Wood and Mark Prior, as the Cubs led the division down the stretch.", answer the following question. Note that the answer is present within the text. Question: what did the cubs do in 2002 that was sub par?
A:
played
