<span>It was Article 231 that came to be called the War Guilt
clause that held Germany responsible for causing the war. It humiliated the Germans and they were very
angry about it. It also forced the
Germans to pay for damages caused by the war.
This bitter resentment among the Germans would later be used by Adolf
Hitler to rally the German people under his leadership and led to the rise of

Answer: Reduction in labor shortages(D)
Explanation:
Migration is the movement of people from one geographicsl area to another. It could be the movement of people from one country to another or from one state to another.
Migration can lead to the disagreement between different religious groups. Due to the influx of people into an area, there can be religious conflicts when the people share different opinions regarding their religion.
Migration can also lead to increase in the cost of health care. As there are more people in the state, there'll be more cases of sick people or people who need medical attention. Migration can also lead to overcrowding in cities because of the larger number of people.
Reduction in labor shortages is an advantage of migration. Migration means there'll be more labor supply and firms can employ the available workers. This will lead to labor shortages.
To combat the threat of tropical diseases such as malaria and yellow fever, the United States decided to use new measures to eradicate the disease before the construction of the Panama Canal. Under the leadership of Colonel William Crawford Gorgas, many changes were made. When it was discovered that mosquitoes were the source of the disease, Gorgas who was appointed as the head of hospital and sanitation, he made sure that containers with stagnant water were removed because mosquitoes lay their eggs there. He also built domestic water systems to eliminate the need to collect rain water. Prophylactic Quinine was supplied to the people in the area and fumigation and oiling of streams were launched. Those who were sick were quarantined and workers would sleep in screened structures so that mosquitoes would not be able to bite them. These programs resulted in the successful elimination of tropical diseases in the area and the health of workers improved.
