As you can see above, the introduction did not give you enough clues to guess what machine is used as context in this unit. Look at the pictures below to see if you can identify the machine. If not, don´t be sad; by doing this task, you will get enough information to be a 100% sure what machine is discussed. Be careful: the task is designed for you to practise scanning, which is one of the methods of speed reading. Therefore, unlike other tasks, this one has a time limit set.
