Answer the following question: Read the article and select the best answer. Article: On the first day of the New Year 2013, I made up my mind to go to Thailand to teach English as a volunteer. Fresh out of college with the world at my fingertips, all I cared about was travelling and seeing the world. Little did I know how awesome my life would be in the coming months! My journey began with the attendance of TESOL certification course in my home state of Florida last February. After 3 weekends of study and another 40 hours' post-study online, I received my TESOL certificate. I was put in touch with Philip, who is Program Director of the Teach in Thailand. In close consultation with Philip, I chose my employment school and after many months of excitement, I finally boarded my plane to Thailand in early April, and set off on an adventure! After a few weeks of single travel, I met up with Philip and the other new teachers in my program in Bangkok. It was great to meet other people who were on the same journey as me, see some cool sights and hang out in Thailand's cities! Directly after that, I attended the week-long seminar , which is included in the Teach in Thailand Program. At the end of the seminar, I was transported to my employment school---Anuban Buriram Primary School. I truly love my job--- I teach Grades 5 and 6 and I have the cleverest and most motivated kids in the world. It's a truly fantastic thing that you can see the difference you make in someone else's life, right in front of you! The city Buriram is small, surrounded with green rice fields. People here are more friendly than anyone I've ever met--I've never been anywhere where a smile is so easily received, where everyone you pass is so eager to say "Hello" and "Good morning". I've been taken out to countless dinners, and been lent a guitar, a digital camera, and even a motorbike, and I am constantly given little Thai treats and the most delicious fresh fruits many times a week. I only hope to pay it forward in the future. Question: To teach English in a foreign country, one has to _ .
