Good answers.

Answer #1 is fine, and true. The actual impetus for U.S. troops to move into Mexico was a Mexican raid on a New Mexico town.

Oh, I meant that for your question above. Your answers here are very good, as Ms. Sue has said.

To get the answer to the question of how Germany's use of unrestricted submarine warfare led to American entry into World War I, you can start by researching the history of World War I. Look for information about Germany's use of unrestricted submarine warfare and its impact on American involvement. You can find reliable sources such as history textbooks, academic journals, and reputable websites.

Once you have gathered enough information, you can analyze the events and consequences. Germany's use of unrestricted submarine warfare meant that they were attacking any ship, including civilian vessels, without warning or ensuring the safety of passengers or crew. This policy directly affected American interests because German submarines sank several American merchant ships, resulting in the loss of American lives and property.

One significant event was the sinking of the British ocean liner RMS Lusitania in 1915, which had 128 Americans on board. The attack generated public outrage in the United States and increased pressure for the U.S. to enter the war on the side of the Allies.

To understand how Congress ensured that the military had enough troops to fight World War I, you can research the selective service system and conscription during that time. Look for information on the legal measures taken by Congress and how they implemented conscription.

The United States employed a draft system, also known as selective service, to meet the military's manpower needs. In 1917, Congress passed the Selective Service Act, which required all men between the ages of 21 and 30 to register for military service. The act allowed for the conscription of men into the armed forces, and those who were drafted were obligated to serve.

To find information on how Congress ensured the military had enough troops, you can consult primary sources like legislative records, historical documents, and government reports. Additionally, secondary sources such as history books and academic articles can provide analysis and context.

By researching these topics and exploring different sources, you can gain a comprehensive understanding of how Germany's submarine warfare influenced American entry into World War I and how Congress ensured that enough troops were available to fight the war.
