I suppose the C is right, because at that time,Spain and Portugal take advantage of slave and cane to be rich, they buy the black people from African to plant sugar cane.
Answer:
Migration is variously characterized as an important determinant of violent conflict and political instability, national power, imperial expansion, ethnic conflict, radicalism, terrorism, environmental degradation, and economic growth or stagnation. In high immigration receiving states such as Australia and the United States—among the world's most inclusive migrant incorporation regimes—immigration increasingly complicates foreign policy making choices, and may present challenges to each host nation's internal cohesion.. Issues such as dual nationality, social exclusion, multiculturalism, and fear of international terrorism—especially in a post-9/11 context—generate considerable political heat and public debate.
2nd paragraph: Combatants in the immigration debate start from very different world views – not only emphasizing different values but almost speaking different languages. To avoid destructive backlashes, reformers must understand and respect the values and perspectives of all groups involved in public debates.Immigration—and public policies to manage it—arouses strong emotions and fierce social and political battles, not just in the United States but in most other countries across the world. Why is this true? Each nation has its own issues that inspire or enrage, of course, but there are widespread, underlying patterns that can be identified and taken into consideration by reformers.
The Battle of Midway gave the allies an advantage in the pacific. This is because the US forces there destroyed four aircraft carriers, causing major damage to Japanese naval air forces to the point they couldn’t replace them in time before the war ended.
Here are why the other answers are incorrect:
The island of Midway was actually under US control before the attack, and was too far from Japan for attacks to be held there. However, it was a crucial airbase that had to be kept for control of the local region.
The Japanese took a few more years to surrender, but some historians consider this battle to be a turning point in the pacific campaign.
The majority of carriers were not destroyed at midway, but as stated above, the destruction of four proved to be a crucial victory, since the Japanese couldn’t replace them in a timely manner.
Hope this helps!
