Input: Read this: Off-grid PV systems have traditionally used rechargeable batteries to store excess electricity. With grid-tied systems, excess electricity can be sent to the transmission grid, while standard grid electricity can be used to meet shortfalls. Net metering programs give household systems a credit for any electricity they deliver to the grid. This is handled by 'rolling back' the meter whenever the home produces more electricity than it consumes. If the net electricity use is below zero, the utility then rolls over the kilowatt hour credit to the next month. Other approaches involve the use of two meters, to measure electricity consumed vs. electricity produced. This is less common due to the increased installation cost of the second meter. Most standard meters accurately measure in both directions, making a second meter unnecessary.
Question: What do off-grid PV systems use to store excess electricity?

Output: rechargeable batteries

Input: Read this: Hoover began using wiretapping in the 1920s during Prohibition to arrest bootleggers. In the 1927 case Olmstead v. United States, in which a bootlegger was caught through telephone tapping, the United States Supreme Court ruled that FBI wiretaps did not violate the Fourth Amendment as unlawful search and seizure, as long as the FBI did not break into a person's home to complete the tapping. After Prohibition's repeal, Congress passed the Communications Act of 1934, which outlawed non-consensual phone tapping, but allowed bugging. In the 1939 case Nardone v. United States, the court ruled that due to the 1934 law, evidence the FBI obtained by phone tapping was inadmissible in court. After the 1967 case Katz v. United States overturned the 1927 case that had allowed bugging, Congress passed the Omnibus Crime Control Act, allowing public authorities to tap telephones during investigations as long as they obtain a warrant beforehand.
Question: What Act did Congress pass to outlaw non-consensual phone tapping?

Output: Communications Act of 1934

Input: Read this: Dallin H. Oaks replaced Wilkinson as president in 1971. Oaks continued the expansion of his predecessor, adding a law school and proposing plans for a new School of Management. During his administration, a new library was also added, doubling the library space on campus. Jeffrey R. Holland followed as president in 1980, encouraging a combination of educational excellence and religious faith at the university. He believed that one of the school's greatest strengths was its religious nature and that this should be taken advantage of rather than hidden. During his administration, the university added a campus in Jerusalem, now called the BYU Jerusalem Center. In 1989, Holland was replaced by Rex E. Lee. Lee was responsible for the Benson Science Building and the Museum of Art on campus. A cancer victim, Lee is memorialized annually at BYU during a cancer fundraiser called the Rex Lee Run. Shortly before his death, Lee was replaced in 1995 by Merrill J. Bateman.
Question: Where is the BUY Jerusalem Center located?

Output: unanswerable

Input: Read this: Napoleon's educational reforms laid the foundation of a modern system of education in France and throughout much of Europe. Napoleon synthesized the best academic elements from the Ancien Regime, The Enlightenment, and the Revolution, with the aim of establishing a stable, well-educated and prosperous society. He made French the only official language. He left some primary education in the hands of religious orders, but he offered public support to secondary education. Napoleon founded a number of state secondary schools (lycees) designed to produce a standardized education that was uniform across France. All students were taught the sciences along with modern and classical languages. Unlike the system during the Ancien Regime, religious topics did not dominate the curriculum, although they were present in addition to teachers from the clergy. Napoleon simply hoped to use religion to produce social stability. He gave special attention to the advanced centers, notably the Ecole Polytechnique, that provided both military expertise and state-of-the-art research in science. Napoleon made some of the first major efforts at establishing a system of secular and public education. The system featured scholarships and strict discipline, with the result being a French educational system that outperformed its European counterparts, many of which borrowed from the French system.
Question: What language did Napoleon make the only official one?

Output:
French
