Q: Question: "Where is Washington university located?" Context: "In 1867, the university opened the first private nonsectarian law school west of the Mississippi River. By 1882, Washington University had expanded to numerous departments, which were housed in various buildings across St. Louis. Medical classes were first held at Washington University in 1891 after the St. Louis Medical College decided to affiliate with the University, establishing the School of Medicine. During the 1890s, Robert Sommers Brookings, the president of the Board of Trustees, undertook the tasks of reorganizing the university's finances, putting them onto a sound foundation, and buying land for a new campus." Answer:
A: west of the Mississippi River

Q: Question: "What causes a reactance of 5%?" Context: "Instead, it is often desired to have an antenna whose impedance does not vary so greatly over a certain bandwidth. It turns out that the amount of reactance seen at the terminals of a resonant antenna when the frequency is shifted, say, by 5%, depends very much on the diameter of the conductor used. A long thin wire used as a half-wave dipole (or quarter wave monopole) will have a reactance significantly greater than the resistive impedance it has at resonance, leading to a poor match and generally unacceptable performance. Making the element using a tube of a diameter perhaps 1/50 of its length, however, results in a reactance at this altered frequency which is not so great, and a much less serious mismatch which will only modestly damage the antenna's net performance. Thus rather thick tubes are typically used for the solid elements of such antennas, including Yagi-Uda arrays." Answer:
A: frequency is shifted

Q: Question: "When did the Romans adjust to new needs in the navy?" Context: "After having declined in size following the subjugation of the Mediterranean, the Roman navy underwent short-term upgrading and revitalisation in the late Republic to meet several new demands. Under Caesar, an invasion fleet was assembled in the English Channel to allow the invasion of Britannia; under Pompey, a large fleet was raised in the Mediterranean Sea to clear the sea of Cilician pirates. During the civil war that followed, as many as a thousand ships were either constructed or pressed into service from Greek cities." Answer:
A: following the subjugation of the Mediterranean

Q: Question: "What did the Karmpa deliver to the capital" Context: "Despite this glowing message by the Emperor, Chan writes that a year later in 1446, the Ming court cut off all relations with the Karmapa hierarchs. Until then, the court was unaware that Deshin Shekpa had died in 1415. The Ming court had believed that the representatives of the Karma Kagyu who continued to visit the Ming capital were sent by the Karmapa." Answer:
A:
representatives
