                       choices = c("Step1", "Step2", "Step3"))

ord <- ordering(identifier = "id_task_1234",
             title = "Order Task",
             choices = c("Step1", "Step2", "Step3"),

             content = list("<p>Set the right order</p>"),
             prompt = "Plain text, can be used instead of content",
             points = 2,
             points_per_answer = FALSE,
             shuffle = FALSE,
             feedback = list(new("WrongFeedback",
                                   content = list("Wrong answer"))),
             calculator = "scientific-calculator",
