Problem: 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]
What year saw the death of Gundobad?
The answer is the following: 516

The uneasy alliance of Carranza, Obregon, Villa, and Zapata eventually led the rebels to victory. The fight against Huerta formally ended on August 15, 1914, when Alvaro Obregon signed a number of treaties in Teoloyucan in which the last of Huerta's forces surrendered to him and recognized the constitutional government. On August 20, 1914, Carranza made a triumphal entry into Mexico City. Carranza (supported by Obregon) was now the strongest candidate to fill the power vacuum and set himself up as head of the new government. This government successfully printed money, passed laws, etc.
The fight against Huerta formally ended on which date?
August 15, 1914

Input: John Kerry
Kerry chaired the Senate Select Committee on POW/MIA Affairs from 1991 to 1993. The committee's report, which Kerry endorsed, stated there was "no compelling evidence that proves that any American remains alive in captivity in Southeast Asia." In 1994 the Senate passed a resolution, sponsored by Kerry and fellow Vietnam veteran John McCain, that called for an end to the existing trade embargo against Vietnam; it was intended to pave the way for normalization. In 1995, President Bill Clinton normalized diplomatic relations with the country of Vietnam.

When did Bill Clinton normalize relations with Vietnam?
Output: 1995

Input: Article: A series of swift Prussian and German victories in eastern France, culminating in the Siege of Metz and the Battle of Sedan, saw the army of the Second Empire decisively defeated (Napoleon III had been captured at Sedan on 2 September). A Government of National Defence declared the Third Republic in Paris on 4 September and continued the war and for another five months, the German forces fought and defeated new French armies in northern France. Following the Siege of Paris, the capital fell on 28 January 1871 and then a revolutionary uprising called the Paris Commune seized power in the capital and held it for two months, until it was bloodily suppressed by the regular French army at the end of May 1871.

Now answer this question: A series of Prussian and German victories took place in what part of France?

Output: eastern France

Article: From the early 12th century, French builders developed the Gothic style, marked by the use of rib vaults, pointed arches, flying buttresses, and large stained glass windows. It was used mainly in churches and cathedrals, and continued in use until the 16th century in much of Europe. Classic examples of Gothic architecture include Chartres Cathedral and Reims Cathedral in France as well as Salisbury Cathedral in England. Stained glass became a crucial element in the design of churches, which continued to use extensive wall-paintings, now almost all lost.

Question: What is a notable English Gothic cathedral?
Ans: Salisbury Cathedral

Input: Insect
Although pest insects attract the most attention, many insects are beneficial to the environment and to humans. Some insects, like wasps, bees, butterflies and ants, pollinate flowering plants. Pollination is a mutualistic relationship between plants and insects. As insects gather nectar from different plants of the same species, they also spread pollen from plants on which they have previously fed. This greatly increases plants' ability to cross-pollinate, which maintains and possibly even improves their evolutionary fitness. This ultimately affects humans since ensuring healthy crops is critical to agriculture. As well as pollination ants help with seed distribution of plants. This helps to spread the plants which increases plant diversity. This leads to an overall better environment. A serious environmental problem is the decline of populations of pollinator insects, and a number of species of insects are now cultured primarily for pollination management in order to have sufficient pollinators in the field, orchard or greenhouse at bloom time.:240243 Another solution, as shown in Delaware, has been to raise native plants to help support native pollinators like L. vierecki. Insects also produce useful substances such as honey, wax, lacquer and silk. Honey bees have been cultured by humans for thousands of years for honey, although contracting for crop pollination is becoming more significant for beekeepers. The silkworm has greatly affected human history, as silk-driven trade established relationships between China and the rest of the world.

Many insects are what to the environment?
Output:
beneficial
