Directions: Read the following passage. Answer the questions according to the in formation given in the

passage and the required words limit. Write your answers on your answer sheet.

     When students all over the world finish high school, it is a very important time in their lives. After years

of full-time schooling they must decide what next step to take as they enter adulthood, and young people

from different countries often face different options for what that next step will be.

     For many students, the obvious choice is to enter college or university to continue their education. Some

know what they want to study, and enter specialized programs like law school or medical school. Other

students choose to study something more general, like English or history, and spend many more years in

school before entering the job market. Going to graduate school can be very expensive, but for many people

education is an essential step to earning a high-paying job.

     Another option is to begin working right away. After high school, many students in America choose to

find a job or enter a "trade school" to learn special skills to help them find work. This way, young people can

learn skills that can help them make a career, and they can even start their own business to make more money.

     Many young people from European countries choose to take a "gap year," meaning they travel around the

world before going to university or getting a job. During this time they can get life experience and think about

what career or education to pursue, but it may be very expensive to travel for such a long time.

     Finally, another option for students is to serve their country or community through military or volunteer

service. In some countries, like Israel, most young people spend time in the military after finishing high school.

Sometimes students can get money for university by spending time in the military or by serving their

communities through volunteer work.
