Here is a question about this article: However a log-periodic dipole array consists of a number of dipole elements of different lengths in order to obtain a somewhat directional antenna having an extremely wide bandwidth: these are frequently used for television reception in fringe areas. The dipole antennas composing it are all considered "active elements" since they are all electrically connected together (and to the transmission line). On the other hand, a superficially similar dipole array, the Yagi-Uda Antenna (or simply "Yagi"), has only one dipole element with an electrical connection; the other so-called parasitic elements interact with the electromagnetic field in order to realize a fairly directional antenna but one which is limited to a rather narrow bandwidth. The Yagi antenna has similar looking parasitic dipole elements but which act differently due to their somewhat different lengths. There may be a number of so-called "directors" in front of the active element in the direction of propagation, and usually a single (but possibly more) "reflector" on the opposite side of the active element.
What is the answer to this question: What is a variation of this antenna type?

So... Yagi-Uda Antenna

Here is a question about this article: A combination of urban and suburban development, the West Side is generally defined as the area west of I-10. Western Tucson encompasses the banks of the Santa Cruz River and the foothills of the Tucson Mountains, and includes the International Wildlife Museum, Sentinel Peak, and the Marriott Starr Pass Resort & Spa, located in the wealthy enclave known as Starr Pass. Moving past the Tucson Mountains, travelers find themselves in the area commonly referred to as "west of" Tucson or "Old West Tucson". A large undulating plain extending south into the Altar Valley, rural residential development predominates, but here you will also find major attractions including Saguaro National Park West, the Arizona-Sonora Desert Museum, and the Old Tucson Studios movie set/theme park.
What is the answer to this question: What is the name of the movie set in Old West Tuscon?

So... Old Tucson Studios

Here is a question about this article: While technically referring to the era before Christopher Columbus' voyages of 1492 to 1504, in practice the term usually includes the history of American indigenous cultures until Europeans either conquered or significantly influenced them, even if this happened decades or even centuries after Columbus' initial landing. "Pre-Columbian" is used especially often in the context of discussing the great indigenous civilizations of the Americas, such as those of Mesoamerica (the Olmec, the Toltec, the Teotihuacano, the Zapotec, the Mixtec, the Aztec, and the Maya civilizations) and those of the Andes (Inca Empire, Moche culture, Muisca Confederation, Canaris).
What is the answer to this question: When was Columbus' first voyage?

So...
1492
