Questions 20 to 23 are based on the following passage. 

Traveling to another country where you know no one can be very challenging and frustrating.It’s even worse if you don’t know the language. When I had the opportunity to go to the UnitedStates to learn English, I realized how ignorant I was and how difficult a new life could be. 

It was very challenging for me to get used to the language and the way people lived. On myfirst day of school, while entering the classroom, Mr. Erickson asked me, “What’s your name?”Very quietly and shy I replied, “Yes.”The classroom filled up with laugher. I was confused butsoon I understood. It was difficult for me to get used to the accent. Whenever I wanted to ask orsay something in English, the students should start laughing and making fun of me. I had troublein school because I barely received help from my teachers and classmates. I would cry myself tosleep for almost one year.All I wanted to do was go back to Mexico because I just couldn ’t dealwith things anymore. I hated school so bad. 

However, throughout the years I started to improve. My writing skills increased, mypronunciation was clearer, and my grades got better. I felt so proud of myself and of what I hadaccomplished. My ignorance decreased by a lot. Coming here made me a better person becausenow I know much more. It’s difficult at the beginning of the journey but throughout time you seehow things will get better sooner or later. I didn’t give up; instead I kept on trying for my parentsand for myself. I wouldn’t change anything that happened to me because I believe that everythinghappens for a reason. Thanks to everything, I’m standing where I am.
