Problem: Melbourne:

An influx of interstate and overseas migrants, particularly Irish, German and Chinese, saw the development of slums including a temporary "tent city" established on the southern banks of the Yarra. Chinese migrants founded the Melbourne Chinatown in 1851, which remains the longest continuous Chinese settlement in the Western World. In the aftermath of the Eureka Stockade, mass public support for the plight of the miners resulted in major political changes to the colony, including changes to working conditions across local industries including mining, agriculture and manufacturing. The nationalities involved in the Eureka revolt and Burke and Wills expedition gave an indication of immigration flows in the second half of the nineteenth century.

Which ethninticities contributed an influx of interstate and overseas migrants to Melbourne?
---
A: Irish, German and Chinese

Problem: Franco-Prussian War:

On the French side, planning after the disaster at Wissembourg had become essential. General Le Buf, flushed with anger, was intent upon going on the offensive over the Saar and countering their loss. However, planning for the next encounter was more based upon the reality of unfolding events rather than emotion or pride, as Intendant General Wolff told him and his staff that supply beyond the Saar would be impossible. Therefore, the armies of France would take up a defensive position that would protect against every possible attack point, but also left the armies unable to support each other.

Which disaster made French planning supremely essential?
---
A: the disaster at Wissembourg

Problem: Molotov%E2%80%93Ribbentrop Pact:

Most notably, there was also a secret protocol to the pact, revealed only after Germany's defeat in 1945, although hints about its provisions were leaked much earlier, e.g., to influence Lithuania. According to said protocol Romania, Poland, Lithuania, Latvia, Estonia and Finland were divided into German and Soviet "spheres of influence". In the north, Finland, Estonia and Latvia were assigned to the Soviet sphere. Poland was to be partitioned in the event of its "political rearrangement"the areas east of the Pisa, Narev, Vistula and San rivers going to the Soviet Union while Germany would occupy the west. Lithuania, adjacent to East Prussia, would be in the German sphere of influence, although a second secret protocol agreed to in September 1939 reassigned the majority of Lithuania to the USSR. According to the secret protocol, Lithuania would be granted the city of Vilnius its historical capital, which was under Polish control during the inter-war period. Another clause of the treaty was that Germany would not interfere with the Soviet Union's actions towards Bessarabia, then part of Romania; as the result, Bessarabia was joined to the Moldovan ASSR, and become the Moldovan SSR under control of Moscow.

Bessarabia eventually became under the control of which country?
---
A: Soviet Union
