Article: Bell's patent 174,465, was issued to Bell on March 7, 1876, by the U.S. Patent Office. Bell's patent covered "the method of, and apparatus for, transmitting vocal or other sounds telegraphically ... by causing electrical undulations, similar in form to the vibrations of the air accompanying the said vocal or other sound" [N 16] Bell returned to Boston the same day and the next day resumed work, drawing in his notebook a diagram similar to that in Gray's patent caveat.

Question: Bell sketched a design that looked like the work of who?
Ans: Gray

Article: The Kinsey scale has been praised for dismissing the dichotomous classification of sexual orientation and allowing for a new perspective on human sexuality. However, the scale has been criticized because it is still not a true continuum. Despite seven categories being able to provide a more accurate description of sexual orientation than a dichotomous scale it is still difficult to determine which category individuals should be assigned to. In a major study comparing sexual response in homosexual males and females, Masters and Johnson discuss the difficulty of assigning the Kinsey ratings to participants. Particularly, they found it difficult to determine the relative amount heterosexual and homosexual experience and response in a person's history when using the scale. They report finding it difficult to assign ratings 2-4 for individuals with a large number of heterosexual and homosexual experiences. When, there is a lot of heterosexual and homosexual experiences in one's history it becomes difficult for that individual to be fully objective in assessing the relative amount of each.

Question: In a study by Masters and Johnson what did the find difficult about KIneys ratings?
Ans: to determine the relative amount heterosexual and homosexual experience and response in a person's history when using the scale

Article: In order to view MUSE encoded discs, it was necessary to have a MUSE decoder in addition to a compatible player. There are televisions with MUSE decoding built-in and set top tuners with decoders that can provide the proper MUSE input. Equipment prices were high, especially for early HDTVs which generally eclipsed US$10,000, and even in Japan the market for MUSE was tiny. Players and discs were never officially sold in North America, although several distributors imported MUSE discs along with other import titles. Terminator 2: Judgment Day, Lawrence of Arabia, A League of Their Own, Bugsy, Close Encounters of the Third Kind, Bram Stoker's Dracula and Chaplin were among the theatrical releases available on MUSE LDs. Several documentaries, including one about Formula One at Japan's Suzuka Circuit were also released.

Question: What was the price for early HDTVs?
Ans: US$10,000

Article: The end result is that the resonant antenna will efficiently feed a signal into the transmission line only when the source signal's frequency is close to that of the design frequency of the antenna, or one of the resonant multiples. This makes resonant antenna designs inherently narrowband, and they are most commonly used with a single target signal. They are particularly common on radar systems, where the same antenna is used for both broadcast and reception, or for radio and television broadcasts, where the antenna is working with a single frequency. They are less commonly used for reception where multiple channels are present, in which case additional modifications are used to increase the bandwidth, or entirely different antenna designs are used.

Question: For use with more than one channel changes are made to increase what property?
Ans:
bandwidth
