During the late 1800s the chinese immigration rate dramatically
decreased because of new legislation
decrease because of the war in china
increased because of a gold rush
increase because of job opportunities

The good answer is: It decreased because of new legislation.

Explanation:

In 1882, Congress passed the Chinese Exclusion Act. It suspended for 10 years the immigration of Chinese skilled and unskilled workers into the USA. Every Chinese person travelling in the United States had to carry a certificate telling his or her status. Cultural differences and ethnic discrimination were the reasons behind that move.  

the topic i chose to write about was " why scuba diving is so popular". the topic is suitable for the audience because it is the easiest to develop and explain, it can be explained in a simpler more conversational manner, it does not require the use of too many technical words, and the final reason for selecting this topic is that it is the one most people can relate to, you might not know too much about scuba diving, but you could probably agree that it is very popular. the purpose of the writing about this topic is to convince more people about the benefits both for the body and the mind that   scuba diving can have on a person. it can you keep fit since it requires a lot of energy when swimming underwater; it also you relax because you forget about the world when you are underwater being mesmerized by the underwater world. i would write this paper in the summer, a perfect time to give scuba diving a try if a person has not done it yet.
