Input: Read this: 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.
Question: Where was an experimental 6kV DC railway built?

Output: the Soviet Union

Input: Read this: A pater familias was the senior priest of his household. He offered daily cult to his lares and penates, and to his di parentes/divi parentes at his domestic shrines and in the fires of the household hearth. His wife (mater familias) was responsible for the household's cult to Vesta. In rural estates, bailiffs seem to have been responsible for at least some of the household shrines (lararia) and their deities. Household cults had state counterparts. In Vergil's Aeneid, Aeneas brought the Trojan cult of the lares and penates from Troy, along with the Palladium which was later installed in the temple of Vesta.
Question: Which individual in the household was responsible for the Vesta cult?

Output: wife

Input: Read this: Religious law centered on the ritualised system of honours and sacrifice that brought divine blessings, according to the principle do ut des ("I give, that you might give"). Proper, respectful religio brought social harmony and prosperity. Religious neglect was a form of atheism: impure sacrifice and incorrect ritual were vitia (impious errors). Excessive devotion, fearful grovelling to deities and the improper use or seeking of divine knowledge were superstitio. Any of these moral deviations could cause divine anger (ira deorum) and therefore harm the State. The official deities of the state were identified with its lawful offices and institutions, and Romans of every class were expected to honour the beneficence and protection of mortal and divine superiors. Participation in public rites showed a personal commitment to their community and its values.
Question: What form of religion was atheism considered to be?

Output: Religious neglect

Input: Read this: Attempts are frequently made to regulate emotion according to the conventions of the society and the situation based on many (sometimes conflicting) demands and expectations which originate from various entities. The emotion of anger is in many cultures discouraged in girls and women, while fear is discouraged in boys and men. Expectations attached to social roles, such as "acting as man" and not as a woman, and the accompanying "feeling rules" contribute to the differences in expression of certain emotions. Some cultures encourage or discourage happiness, sadness, or jealousy, and the free expression of the emotion of disgust is considered socially unacceptable in most cultures. Some social institutions are seen as based on certain emotion, such as love in the case of contemporary institution of marriage. In advertising, such as health campaigns and political messages, emotional appeals are commonly found. Recent examples include no-smoking health campaigns and political campaigns emphasizing the fear of terrorism.
Question: What social institution is associated with the emotion of love?

Output:
marriage
