Here is a question about this article: The quarter-wave elements imitate a series-resonant electrical element due to the standing wave present along the conductor. At the resonant frequency, the standing wave has a current peak and voltage node (minimum) at the feed. In electrical terms, this means the element has minimum reactance, generating the maximum current for minimum voltage. This is the ideal situation, because it produces the maximum output for the minimum input, producing the highest possible efficiency. Contrary to an ideal (lossless) series-resonant circuit, a finite resistance remains (corresponding to the relatively small voltage at the feed-point) due to the antenna's radiation resistance as well as any actual electrical losses.
What is the answer to this question: How would you describe a current that has maximum efficiency?
****
So... minimum reactance


Here is a question about this article: At the Salon d'Automne of the same year, in addition to the Indépendants group of Salle 41, were exhibited works by André Lhote, Marcel Duchamp, Jacques Villon, Roger de La Fresnaye, André Dunoyer de Segonzac and František Kupka. The exhibition was reviewed in the October 8, 1911 issue of The New York Times. This article was published a year after Gelett Burgess' The Wild Men of Paris, and two years prior to the Armory Show, which introduced astonished Americans, accustomed to realistic art, to the experimental styles of the European avant garde, including Fauvism, Cubism, and Futurism. The 1911 New York Times article portrayed works by Picasso, Matisse, Derain, Metzinger and others dated before 1909; not exhibited at the 1911 Salon. The article was titled The "Cubists" Dominate Paris' Fall Salon and subtitled Eccentric School of Painting Increases Its Vogue in the Current Art Exhibition - What Its Followers Attempt to Do.
What is the answer to this question: List the artists who were featured in the Salon d'Automne? 
****
So... André Lhote, Marcel Duchamp, Jacques Villon, Roger de La Fresnaye, André Dunoyer de Segonzac and František Kupka


Here is a question about this article: The 1980s ushered in the age of desktop computing. The new computers empowered their users with spreadsheets like Lotus 1-2-3 and database software like dBASE. The dBASE product was lightweight and easy for any computer user to understand out of the box. C. Wayne Ratliff the creator of dBASE stated: "dBASE was different from programs like BASIC, C, FORTRAN, and COBOL in that a lot of the dirty work had already been done. The data manipulation is done by dBASE instead of by the user, so the user can concentrate on what he is doing, rather than having to mess with the dirty details of opening, reading, and closing files, and managing space allocation." dBASE was one of the top selling software titles in the 1980s and early 1990s.
What is the answer to this question: Why was dBASE unique?
****
So...
data manipulation is done by dBASE
