Hayek was one of the leading academic critics of collectivism in the 20th century. Hayek argued that all forms of collectivism (even those theoretically based on voluntary co-operation) could only be maintained by a central authority of some kind. In Hayek's view, the central role of the state should be to maintain the rule of law, with as little arbitrary intervention as possible. In his popular book, The Road to Serfdom (1944) and in subsequent academic works, Hayek argued that socialism required central economic planning and that such planning in turn leads towards totalitarianism.
What did Hayek believe was the core responsibility of the state?
A: maintain the rule of law

The Crusaders in the Holy Land also adopted mosaic decoration under local Byzantine influence. During their 12th-century reconstruction of the Church of the Holy Sepulchre in Jerusalem they complemented the existing Byzantine mosaics with new ones. Almost nothing of them survived except the "Ascension of Christ" in the Latin Chapel (now confusingly surrounded by many 20th-century mosaics). More substantial fragments were preserved from the 12th-century mosaic decoration of the Church of the Nativity in Bethlehem. The mosaics in the nave are arranged in five horizontal bands with the figures of the ancestors of Christ, Councils of the Church and angels. In the apses the Annunciation, the Nativity, Adoration of the Magi and Dormition of the Blessed Virgin can be seen. The program of redecoration of the church was completed in 1169 as a unique collaboration of the Byzantine emperor, the king of Jerusalem and the Latin Church.
The Byzantine emperor, the king of Jerusalem and the Latin Church came together in what year to redecorate the Church of the Holy Sepulchre?
A: 1169

The elimination of wolves from Yellowstone National Park had profound impacts on the trophic pyramid. Without predation, herbivores began to over-graze many woody browse species, affecting the area's plant populations. In addition, wolves often kept animals from grazing in riparian areas, which protected beavers from having their food sources encroached upon. The removal of wolves had a direct effect on beaver populations, as their habitat became territory for grazing. Furthermore, predation keeps hydrological features such as creeks and streams in normal working order. Increased browsing on willows and conifers along Blacktail Creek due to a lack of predation caused channel incision because they helped slow the water down and hold the soil in place.
Loose soil from lack of trees along the river bed resulted in?
A:
channel incision
