The answer is letter a. It created a too-weak national government. When Congress drafted the nation's first constitution in 1777, it knew that many Americans dreaded a powerful national government. For that reason, the proposed Articles of Confederation created a framework for a loose confederation of states. Within this coalition, each state would retain "sovereignty, freedom, and independence." Also, the Congress was made up of delegates chosen by the states and could conduct foreign affairs, create treaties, proclaim war, uphold an army and a navy, coin money, and establish post offices. However, measures passed by Congress had to be approved by 9 of the 13 states. Since the Articles did not set up an executive branch to carry out the laws or a judicial branch to settle legal questions.
Answer:
Between 1900 and 1915, more than 15 million immigrants arrived in the United States. That was about equal to the number of immigrants who had arrived in the previous 40 years combined. In 1910, three-fourths of New York City's population were either immigrants or first generation Americans (i.e. the sons and daughters of immigrants).
Not only were the numbers of immigrants swelling, the countries from which they came had changed dramatically as well. Unlike earlier immigrants, the majority of the newcomers after 1900 came from non-English speaking European countries. The principal source of immigrants was now southern and eastern Europe, especially Italy, Poland, and Russia, countries quite different in culture and language from the United States, and many immigrants had difficulty adjusting to life here.
At the same time, the United States had difficulty absorbing the immigrants. Most of the immigrants chose to settle in American cities, where jobs were located. As a result, the cities became ever more crowded. In addition, city services often failed to keep up with the flow of newcomers. Most of the immigrants did find jobs, although they often worked in jobs that most native-born Americans would not take. Over time, however, many immigrants succeeded in improving their condition.
