Given the question: Read the following article and select the best answer. Article: Students who want to attend an American university must explain how they will pay for their education. They have to show that they will be able to pay for each year of study. Students have to consider not only the tuition, the cost of classes, but also meals and a place to live in, which is known as room-and-board. They also need money for books and supplies. And they need money to spend on social activities and other things. Educational advisers say foreign students should have enough money in a local bank to pay for at least two months of expenditure . So how much will a year at an American school cost? Generally speaking, the answer is: a lot. A leading state university in the Pacific Northwest will serve as an example. The University of Washington says foreign students are paying more than $36,000 this year. This major research university currently has 2,600 foreign students from more than 100 countries. There are many schools that cost less, but also others that cost more. Its web site says the University of Washington does not offer financial assistance to international students. This is generally true of American schools, especially at the undergraduate level. The international application for the university includes a Statement of Financial Responsibility that must be signed. Students must also provide a bank letter or statement from within the past six months. And they have to name someone who will help with payments. These people must send proof from a bank to show that they have the money. Your government or employer may be able to help you pay all or some of the college costs. A good idea is to ask at least eighteen months before you want to start classes in the United States.
