Input: Read this: In March 1984, Pioneer introduced the first consumer player with a solid-state laser, the LD-700. It was also the first LD player to load from the front and not the top. One year earlier Hitachi introduced an expensive industrial player with a laser diode, but the player, which had poor picture quality due to an inadequate dropout compensator, was made only in limited quantities. After Pioneer released the LD-700, gas lasers were no longer used in consumer players, despite their advantages, although Philips continued to use gas lasers in their industrial units until 1985.
Question: Which company continued to use gas-lasers in industrial models of LD players although they were no longer used in consumer models?

Output: Philips


QUES: Modern electrification systems take AC energy from a power grid which is delivered to a locomotive and converted to a DC voltage to be used by traction motors. These motors may either be DC motors which directly use the DC or they may be 3-phase AC motors which require further conversion of the DC to 3-phase AC (using power electronics). Thus both systems are faced with the same task: converting and transporting high-voltage AC from the power grid to low-voltage DC in the locomotive. Where should this conversion take place and at what voltage and current (AC or DC) should the power flow to the locomotive? And how does all this relate to energy-efficiency? Both the transmission and conversion of electric energy involve losses: ohmic losses in wires and power electronics, magnetic field losses in transformers and smoothing reactors (inductors). Power conversion for a DC system takes place mainly in a railway substation where large, heavy, and more efficient hardware can be used as compared to an AC system where conversion takes place aboard the locomotive where space is limited and losses are significantly higher. Also, the energy used to blow air to cool transformers, power electronics (including rectifiers), and other conversion hardware must be accounted for.

What is the main action AC and DC systems have to deal with?
What is the answer?
ANS: converting and transporting


QUES: The materialist view is perhaps best understood in its opposition to the doctrines of immaterial substance applied to the mind historically, famously by René Descartes. However, by itself materialism says nothing about how material substance should be characterized. In practice, it is frequently assimilated to one variety of physicalism or another.
Was René Descartes an idealist or a materialist?

ANS: materialist


In the years following the dissolution of Yugoslavia, some historians stated that human rights were suppressed in Yugoslavia under Tito, particularly in the first decade up until the Tito-Stalin split. On 4 October 2011, the Slovenian Constitutional Court found a 2009 naming of a street in Ljubljana after Tito to be unconstitutional. While several public areas in Slovenia (named during the Yugoslav period) do already bear Tito's name, on the issue of renaming an additional street the court ruled that:
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Under which ruler do historians argue human rights were suppressed in Yugoslavia?
Ah, so.. Tito


Question: Other local colleges and universities include Concordia University Ann Arbor, a Lutheran liberal-arts institution; a campus of the University of Phoenix; and Cleary University, a private business school. Washtenaw Community College is located in neighboring Ann Arbor Township. In 2000, the Ave Maria School of Law, a Roman Catholic law school established by Domino's Pizza founder Tom Monaghan, opened in northeastern Ann Arbor, but the school moved to Ave Maria, Florida in 2009, and the Thomas M. Cooley Law School acquired the former Ave Maria buildings for use as a branch campus.
Try to answer this question if possible: What Lutheran school did Tom Monaghan found?
Answer: unanswerable


Context and question: Second, Democrats have always elevated their minority floor leader to the speakership upon reclaiming majority status. Republicans have not always followed this leadership succession pattern. In 1919, for instance, Republicans bypassed James R. Mann, R-IL, who had been minority leader for eight years, and elected Frederick Gillett, R-MA, to be Speaker. Mann "had angered many Republicans by objecting to their private bills on the floor;" also he was a protégé of autocratic Speaker Joseph Cannon, R-IL (1903–1911), and many Members "suspected that he would try to re-centralize power in his hands if elected Speaker." More recently, although Robert H. Michel was the Minority Leader in 1994 when the Republicans regained control of the House in the 1994 midterm elections, he had already announced his retirement and had little or no involvement in the campaign, including the Contract with America which was unveiled six weeks before voting day.
How many Demcorats were angry with James R. Mann in 1911?
Answer:
unanswerable
