Final answer:
Many people arriving on Angel Island and Ellis Island were not allowed entry into the United States, although the processes and conditions were different.
Step-by-step explanation:
In the case of Angel Island, many people arriving there were not allowed entry into the United States. Detained for weeks, months, or even years, immigrants faced challenging and obscure interrogations. Angel Island's main goal was to control the flow of Chinese people into the United States.
On the other hand, Ellis Island, opened in 1892, became the port of entry for about half of the immigrants to the United States in the next two decades. Those who purchased regular tickets were entitled to proper sleeping quarters and underwent a short question-based inspection. However, those who could not afford regular tickets were restricted to the steerage section and underwent a more detailed medical and legal inspection, with about 2% being denied entry.
So, when it comes to the statement that many people were not allowed entry, it applies to both Angel Island and Ellis Island, although the processes and conditions were different.
