Recurrence means for something to happen over and over again. It is often used for emphasis. In speeches, it is helpful to repeat specific phrases so they get stuck in the mind of the audience. MLK Jr's speech uses repetition with "I have a dream".
Allusion is a reference to another literary work. The most often text alluded to is the Bible. Rhythm is the sound of the words or the meter. Opinion is not really a rhetorical device.
Cause explains <u>the reason how something has happened or occurred. It helps in finding answers to how an incidence took place</u>. The question one should ask when one sees a cause clue word would be "How did it happen?"
In this way the cause can be answered with answers explaining how it happened. For instance, when Jim asked Tom "How did it happen?", Tom replied "It happened when I kept the candles close to the screen so that I can do a hand shadow puppet".
The detail in the passage that supports the idea that economic life was difficult in China is the following one:
As a result of wars, famine, and political oppression, Chinese immigration to the United States dates back to the mid-1800s.
Chinese immigrants came to the United States looking for better economic opportunities so they could provide for their families and send money to their relatives back home.
