After Christianization, the Roman Catholic Church and local rulers led German expansion and settlement in areas inhabited by Slavs and Balts, known as Ostsiedlung. During the wars waged in the Baltic by the Catholic German Teutonic Knights; the lands inhabited by the ethnic group of the Old Prussians (the current reference to the people known then simply as the "Prussians"), were conquered by the Germans. The Old Prussians were an ethnic group related to the Latvian and Lithuanian Baltic peoples. The former German state of Prussia took its name from the Baltic Prussians, although it was led by Germans who had assimilated the Old Prussians; the old Prussian language was extinct by the 17th or early 18th century. The Slavic people of the Teutonic-controlled Baltic were assimilated into German culture and eventually there were many intermarriages of Slavic and German families, including amongst the Prussia's aristocracy known as the Junkers. Prussian military strategist Karl von Clausewitz is a famous German whose surname is of Slavic origin. Massive German settlement led to the assimilation of Baltic (Old Prussians) and Slavic (Wends) populations, who were exhausted by previous warfare.
Who is a famous German that name has Slavic origins?
****
The answer: Karl von Clausewitz

Paul's Christology has a specific focus on the death and resurrection of Jesus. For Paul, the crucifixion of Jesus is directly related to his resurrection and the term "the cross of Christ" used in Galatians 6:12 may be viewed as his abbreviation of the message of the gospels. For Paul, the crucifixion of Jesus was not an isolated event in history, but a cosmic event with significant eschatological consequences, as in 1 Corinthians 2:8. In the Pauline view, Jesus, obedient to the point of death (Philippians 2:8) died "at the right time" (Romans 4:25) based on the plan of God. For Paul the "power of the cross" is not separable from the Resurrection of Jesus.
Who's Christology focuses on the death and Resurrection?
****
The answer: Paul's Christology

The problem: Answer 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.
How are antennas oriented when arranged with specific spacing?

The answer:
parallel
