What is David’s present job?

In this section, you will hear a monologue. The monologue will be read twice. After the monologue, there will be a one-minute pause. During the pause, read the questions and the four choices marked A, B, C and D, and decide which is the best answer. Then mark the corresponding letter on the answer sheet with a single line through the centre.
    Good evening and thank you for coming to learn something about the Hillside Survival School.
    My name’s David Johnson. I started the school and I’m the school’s chief instructor. I learned my survival skills while I was in the army and since then I’ve used them all over the world. My real aim for this school is to help people not only to discover nature and outdoor life but also to learn and to have fun. We run a variety of courses but our basic survival course lasts a weekend. This course teaches you the basic skills that you need to survive in the wilderness, and during the course you are given a lot of opportunities to practice these skills. This course costs ￡139 per person. If you want an even bigger challenge, our extreme survival course takes place between November and February when conditions are more difficult. These courses also last for a weekend and cost ￡149 per person. The extreme survival course teaches you to survive in a cold and wet environment. The course offers you the chance to push yourself, both physically and mentally. No tents, no gas cookers, just you and the wilderness.
    A few final practical details. You have to be at least 18 years old to come on the course. The full cost of the course needs to be paid at least four weeks before the course begins, and remember that there are discounts for groups of four or more. Well, I hope that gives you some idea of what we do. And now if there are any questions.
