13. The eastern strip that Germany lost to Poland was referred to as the "Polish Corridor." Poland was given this area within the Treaty of Versailles so that it might have access to the sea. What
problems do you think this caused for the Germans of East Prussia?

Germans in East Prussia would have to go through Poland or transport in the Baltic Sea to get to the rest of Germany.

Explanation:

The Polish Corridor that separated East Prussia and Germany was one of the reasons for Hitler's justification over the coastal city of Danzig which was in the Polish Corridor.  It did not connect East Prussians to Germany which was rightfully German territory.

The correct answer to this open question is the following.

Unfortunately, you did not include the two maps. Without them, we do not know your specific reference.

However, trying to help you and after doing some deep research, we can say the maps portray the Spanish, British, and Dutch trade maritime routes from 1750 to 1850. The other map shows the many trade routes in 2010 that practically crossed all over the world.

That is why we can answer that one significant reason for changes in the patterns of global economic interactions from circa 1750 to circa 2000, as illustrated by the two maps are the technology and modernization of means of transportation that today include land, air, and sea.

Trade has been the activity that has developed most rapidly all over the world in those years. Today, there are international organizations and free trade agreements that connect the world through trade.

More people on the planet started to require more products from all places and developed nations exploited natural resources and raw materials and produced more and better goods in their industrialized cities that were exported.

Explanation:

b. The development of diseases in the sixteenth century would support the arguments of the “new generation of historians in the second paragraph because the “new generation of historians” would look at this in relation to european imperialism and see the impact of the european diseases like smallpox that would plague places like modern day united states because of the european immunity, but lack of native immunity.  

c. The “biological competition” contributed to the European imperialism in the Americas by creating a survival of the fittest environment where the europeans brought in diseases like smallpox that had plagued europe generations ago, but infected the native populations and weaken them in both their numbers and their strength, which enabled the Europeans to take control of the new world and develop a dominance while the natives were fighting a disease. This was “biological competition” because the Europeans' immunity was assisting them in fighting the natives' lack thereof.  

A) Ethnic divisions hindered the development of land-based empires in the period 1450-1750. For example, the Manchu people in the Qing Dynasty in China sought to preserve their ethnic values while ruling China, which proved to be an obstacle for them to rule the vast majority of Han Chinese.

B) Ethnic divisions also hindered the development of maritime empires in the period 1450-1750. For example, the ethnic division between the French colonists and the Haitian people led to multiple Haitian rebellions and ultimately the Haitian Revolution against France.

C) Many land-based empires and maritime empires institutionalized hierarchical distinctions amongst different ethnic groups, often with the use of slavery. The European colonists, for instance, made African Americans the lowest class in American society by enslaving them. Similarly, Christians under Ottoman rule are recruited as janissaries. In both examples, the ruling class adopted policies that limit the social mobility of the ethnic groups that are alien to themselves.

In general, because of his numerous achievements, Akbar was awarded the epithet "the Great." The majority of Akbar's achievements military-related.
