Each branch of government has its own specific powers. This is known as separation of powers. Each branch also 'checks' the power of the other two. This is nown as checks and balances. For example the legislative branch (Congress) writes all our laws, but they do
not become official law until the executive (president) signs them. The Supreme Court's job is to interpret laws. If it determines a law
written by Congress and signed by the President is unconstitutional, it has the power to eliminate that law.
The founding fathers divided power in this way for a reason. What is the reason? (two sentences)

angel island immigration station was an immigration station located in san francisco bay which worked from 1910 to 1940. the majority of immigrants that got there were from the asian hemisphere, specifically from china, japan, russia, and south asia, being china the country from where more people arrived.

the number of foreigners arriving at it took the attention of americans who feared the new arrivals would take their jobs. the work opportunities were not abundant due to the economic comedown of 1870 and the asians, as newcomers, were willing to work for cheaper wages. soon they started to be seen as a threat, which led to an increased discrimination against the chinese - the biggest ethnicity arrived at this station until 1915 when japanese immigrants outnumbered them - being considered as unsuitable americans hence their looks and social situation.

at the station, the immigrant's detention may vary depending on how long the interrogation process took: it could be weeks, months, or even years.

finally, in 1940 an explosion destroyed administration building located on the island, so the united states government decided to stop the process.
