For instance, a phased array consists of two or more simple antennas which are connected together through an electrical network. This often involves a number of parallel dipole antennas with a certain spacing. Depending on the relative phase introduced by the network, the same combination of dipole antennas can operate as a "broadside array" (directional normal to a line connecting the elements) or as an "end-fire array" (directional along the line connecting the elements). Antenna arrays may employ any basic (omnidirectional or weakly directional) antenna type, such as dipole, loop or slot antennas. These elements are often identical.
How are antennas oriented when arranged with specific spacing?
parallel


Input: Baptists
Baptists, like other Christians, are defined by doctrine—some of it common to all orthodox and evangelical groups and a portion of it distinctive to Baptists. Through the years, different Baptist groups have issued confessions of faith—without considering them to be creeds—to express their particular doctrinal distinctions in comparison to other Christians as well as in comparison to other Baptists. Most Baptists are evangelical in doctrine, but Baptist beliefs can vary due to the congregational governance system that gives autonomy to individual local Baptist churches. Historically, Baptists have played a key role in encouraging religious freedom and separation of church and state.

Baptists have played a key role in what?
Output: encouraging religious freedom and separation of church and state.


Input: Article: In 1795, the First Russian Orthodox Church was established in Kodiak. Intermarriage with Alaskan Natives helped the Russian immigrants integrate into society. As a result, an increasing number of Russian Orthodox churches gradually became established within Alaska. Alaska also has the largest Quaker population (by percentage) of any state. In 2009 there were 6,000 Jews in Alaska (for whom observance of halakha may pose special problems). Alaskan Hindus often share venues and celebrations with members of other Asian religious communities, including Sikhs and Jains.

Now answer this question: What religious tradition may be a problem for Alaskan Jews?

Output: observance of halakha


Article: Saint Barthélemy was for many years a French commune forming part of Guadeloupe, which is an overseas region and department of France. Through a referendum in 2003, island residents sought separation from the administrative jurisdiction of Guadeloupe, and it was finally accomplished in 2007. The island of Saint Barthélemy became an Overseas Collectivity (COM). A governing territorial council was elected for its administration, which has provided the island with a certain degree of autonomy. The Hotel de Ville, which was the town hall, is now the Hotel de la Collectivité. A senator represents the island in Paris. St. Barthélemy has retained its free port status.

Question: When did the residents of St. Barts file for separation from Guadeloupe?
Ans: 2003


Here is a question about this article: As the election approached, other prominent citizens and politicians from both parties urged Eisenhower to run for president. In January 1948, after learning of plans in New Hampshire to elect delegates supporting him for the forthcoming Republican National Convention, Eisenhower stated through the Army that he was "not available for and could not accept nomination to high political office"; "life-long professional soldiers", he wrote, "in the absence of some obvious and overriding reason, [should] abstain from seeking high political office". Eisenhower maintained no political party affiliation during this time. Many believed he was forgoing his only opportunity to be president; Republican Thomas E. Dewey was considered the other probable winner, would presumably serve two terms, and Eisenhower, at age 66 in 1956, would then be too old.
What is the answer to this question: How old would Eisenhower be in 1956?
****
So... 66


Article: After the Dambusters raid in 1943 an entirely new system was developed that was required to knock down any low-flying aircraft with a single hit. The first attempt to produce such a system used a 50 mm gun, but this proved inaccurate and a new 55 mm gun replaced it. The system used a centralised control system including both search and targeting radar, which calculated the aim point for the guns after considering windage and ballistics, and then sent electrical commands to the guns, which used hydraulics to point themselves at high speeds. Operators simply fed the guns and selected the targets. This system, modern even by today's standards, was in late development when the war ended.

Question: What replaced the 50 millimeter gun that was not accurate?
Ans:
a new 55 mm gun
