Here is a question about this article: 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.
What is the answer to this question: How many antenna would make up a phased array?

So... two or more

Here is a question about this article: The creation of the Federal Republic of Germany in 1949 was through the unification of the western states (which were previously under American, British, and French administration) created in the aftermath of World War II. Initially, in 1949, the states of the Federal Republic were Baden, Bavaria (in German: Bayern), Bremen, Hamburg, Hesse (Hessen), Lower Saxony (Niedersachsen), North Rhine Westphalia (Nordrhein-Westfalen), Rhineland-Palatinate (Rheinland-Pfalz), Schleswig-Holstein, Württemberg-Baden, and Württemberg-Hohenzollern. West Berlin, while officially not part of the Federal Republic, was largely integrated and considered as a de facto state.
What is the answer to this question: How did this republic come to be?
