1) Why did President Wilson intervene in Mexico?

A: President Wilson intervened in Mexico because he desired to lead by moral example and promote Moral Diplomacy.

2) What incident triggered the beginning of World War I?

A: The assassination of the heir to the Austro-Hungarian throne triggered the beginning of World War I.

yes, I would add to it if I were you. You're not wrong, but there was more to it. Look up Pancho Villa and the Mexican raid on Columbus (Columbia?), New Mexico.

It depends on what is meant by intervention. We did send troops into Mexico after Mexico raided a town in New Mexico. We had been involved with Mexico forever (at least since the Mexican-American War in the 1840s). Wilson supported various contenders for political power in Mexico. His motives for most diplomatic efforts were as you say, his concept of "moral diplomacy".

Your answer for #2 is spot on! Very good.

Should I change my answer for #1, then?

Maybe just explain a little further for #1.

To find the answer to your first question, you can study history books, articles, or other reliable sources that discuss President Wilson's policies and actions during his presidency. These sources will provide you with insights into the motivations and goals behind Wilson's decision to intervene in Mexico.

To answer your second question, you can again refer to history books, articles, or other reliable sources that cover the events leading up to World War I. Specifically, look for information about the assassination of Archduke Franz Ferdinand of Austria-Hungary in Sarajevo, Bosnia on June 28, 1914. This event is considered the trigger for the outbreak of World War I, as it set off a chain reaction of political and military alliances leading to the conflict.

Remember to critically assess the credibility of your sources and look for information from multiple perspectives to get a comprehensive understanding of the events in question.
