Context: Because of the difference in lifestyles between Europe and the US , moving to America was challenging . First of all , the formal English which I had learned in school did not help me in the play yard in making contact with other students . Although we had some distant family that helped us out once we actually got here , to me it still felt like we were in the middle of nowhere for quite a time .

Question: When must have I moved to the US from Europe ?
Options:
0. I must have moved when I was in elementary school .
1. I must have moved when I was in college .
2. I must have moved when I was in middle school .
3. I must have moved when I was in high school .
Answer: 0
