До того момента, когда профессор Бейкер уйдет на пенсию, он преподаст более двадцати разных курсов.
Для того чтобы ответить на этот вопрос, нам нужно разобраться с основными понятиями и представить ситуацию более подробно.
Во-первых, профессор Бейкер – это человек, который занимается преподаванием в университете или колледже. Он обычно специализируется в определенной области знания и преподает свои знания и опыт студентам.
Теперь, когда мы поняли, что такое профессор Бейкер, давайте разберемся, что такое "курсы". Курс – это набор специальных занятий или уроков по определенной теме.
