the passage of the Immigration and Nationality Act.

Explanation:

The Immigration and Nationality Act was passed in 1965 in order to abolish the National Origins Formula. The National Origins Formula had been the basis of immigration policy since the 1920s, and it had attempted to reduce immigration from Asia, Southern Europe and Eastern Europe. However, during the 1960s, this law was criticized for being racially discriminatory. Therefore, the Immigration and Nationality Act was passed in order to eliminate these quotas.

when world war i broke out across europe in 1914, president woodrow wilson proclaimed the united states would remain neutral, and many americans supported this policy of nonintervention. however, public opinion about neutrality started to change after the sinking of the british ocean liner lusitania by a german u-boat in 1915; almost 2,000 people perished, including 128 americans. along with news of the zimmerman telegram threatening an alliance between germany and mexico, wilson asked congress for a declaration of war against germany. the u.s. officially entered the conflict on april 6, 1917.
