Here is a question about this article: To prevent further loss of groundwater, Tucson has been involved in water conservation and groundwater preservation efforts, shifting away from its reliance on a series of Tucson area wells in favor of conservation, consumption-based pricing for residential and commercial water use, and new wells in the more sustainable Avra Valley aquifer, northwest of the city. An allocation from the Central Arizona Project Aqueduct (CAP), which passes more than 300 mi (480 km) across the desert from the Colorado River, has been incorporated into the city's water supply, annually providing over 20 million gallons of "recharged" water which is pumped into the ground to replenish water pumped out. Since 2001, CAP water has allowed the city to remove or turn off over 80 wells.
What is the answer to this question: How long is the CAP?
****
So... more than 300 mi (480 km)

Question: Read this and answer the question

Several Germanic tribes celebrated the returning of the daylight. A predominant deity was during this jubilee driven around in a noisy procession on a ship on wheels. The winter would be driven out, to make sure that fertility could return in spring. A central figure was possibly the fertility goddess Nerthus. Also there are some indications that the effigy of Nerthus or Freyr was placed on a ship with wheels and accompanied by a procession of people in animal disguise and men in women's clothes. Aboard the ship would the marriage of a man and woman be consummated as a fertility ritual.

How was the ship carrying a predominant deity moved around during the jubilee?
Answer: on wheels

Input: Article: The political structure of Western Europe changed with the end of the united Roman Empire. Although the movements of peoples during this period are usually described as "invasions", they were not just military expeditions but migrations of entire peoples into the empire. Such movements were aided by the refusal of the western Roman elites to support the army or pay the taxes that would have allowed the military to suppress the migration. The emperors of the 5th century were often controlled by military strongmen such as Stilicho (d. 408), Aspar (d. 471), Ricimer (d. 472), or Gundobad (d. 516), who were partly or fully of non-Roman background. When the line of western emperors ceased, many of the kings who replaced them were from the same background. Intermarriage between the new kings and the Roman elites was common. This led to a fusion of Roman culture with the customs of the invading tribes, including the popular assemblies that allowed free male tribal members more say in political matters than was common in the Roman state. Material artefacts left by the Romans and the invaders are often similar, and tribal items were often modelled on Roman objects. Much of the scholarly and written culture of the new kingdoms was also based on Roman intellectual traditions. An important difference was the gradual loss of tax revenue by the new polities. Many of the new political entities no longer supported their armies through taxes, instead relying on granting them land or rents. This meant there was less need for large tax revenues and so the taxation systems decayed. Warfare was common between and within the kingdoms. Slavery declined as the supply weakened, and society became more rural.[F]

Now answer this question: The loss of what led to the differentiation between the Western Roman Empire and the new kingdoms?

Output:
tax revenue
