II. Read the article about the life of a supermarket manager. Choose the best word A, B or C for each space. THE LIFE OF A SUPERMARKET MANAGER Jonathan Matthews left school at seventeen, went to college and then worked in his father's mini-market. After two years, he went to work for Bargain Foods and then he joined Saver Mall as a trainee manager. Three years later, he got his present job as a supermarket manager with Saver Mall. This is what he told us about his job: “The supermarket where I am manager is in west London but I spend most of my time travelling by road to Saver Mall supermarkets all over Britain. I need to see things in our other supermarkets. I also go to lots of meetings. My work hours change every week because Saver Mall is open 24 hours a day. Last week I worked from 3 p.m. to 11 p.m. but this week I need to be at work from 7 a.m. to 3 p.m. The first thing I do each day is check my emails. Sometimes I go to different countries to check how supermarkets are doing. That's my favorite part of the job! But I like my work in London too. Travelling can be very hard work. When I get back from a journey, I usually go straight to bed. I earn quite good money and I'm happy working for Saver Mall.” 1. When Jonathan first worked for Saver Mall, he was ________.
