Problem: It is best for the receiving antenna to match the polarization of the transmitted wave for optimum reception. Intermediate matchings will lose some signal strength, but not as much as a complete mismatch. A circularly polarized antenna can be used to equally well match vertical or horizontal linear polarizations. Transmission from a circularly polarized antenna received by a linearly polarized antenna (or vice versa) entails a 3 dB reduction in signal-to-noise ratio as the received power has thereby been cut in half.
A transmission can cause reduction in what?
The answer is the following: signal-to-noise ratio

Problem: The State of the Union Addresses and other presidential speeches are translated to Spanish, following the precedent set by the Bill Clinton administration.

Problem: ASCII itself was first used commercially during 1963 as a seven-bit teleprinter code for American Telephone & Telegraph's TWX (TeletypeWriter eXchange) network. TWX originally used the earlier five-bit ITA2, which was also used by the competing Telex teleprinter system. Bob Bemer introduced features such as the escape sequence. His British colleague Hugh McGregor Ross helped to popularize this work –  according to Bemer, "so much so that the code that was to become ASCII was first called the Bemer-Ross Code in Europe". Because of his extensive work on ASCII, Bemer has been called "the father of ASCII."
Who is the father of ASCII?
The answer is the following: Bob Bemer

Problem: Northwestern was founded in 1851 by John Evans, for whom the City of Evanston is named, and eight other lawyers, businessmen and Methodist leaders. Its founding purpose was to serve the Northwest Territory, an area that today includes the states of Ohio, Indiana, Illinois, Michigan, Wisconsin and parts of Minnesota. Instruction began in 1855; women were admitted in 1869. Today, the main campus is a 240-acre (97 ha) parcel in Evanston, along the shores of Lake Michigan just 12 miles north of downtown Chicago. The university's law, medical, and professional schools are located on a 25-acre (10 ha) campus in Chicago's Streeterville neighborhood. In 2008, the university opened a campus in Education City, Doha, Qatar with programs in journalism and communication.
What is the name of the city located 12 miles north of Northwestern?
The answer is the following:
Chicago
