You should spend about 20 minutes on this task. The illustration below shows the process of tying a bow tie. Write a report explaining to a university lecturer how to tie his bow tie. Write at least 150 words.

Sample Answer 1:
The diagram illustrates how to knot a bow tie in eight stages.
To begin with, the tie should be placed around the neck, with one end slightly longer than the other. Then place the longer end over the other and pass it upwards and behind the point where the two ends cross.
Next, take the other end of the tie and bend it twice to form an ‘S’ shape. Bring the longer end down and in front, so that it holds the ‘S’ curve in place. Now comes the trickiest part of the process. Take the long end of the tie and form a similar ‘S’ shape before passing it through the narrow gap behind the other end. This creates a knot and the bow should now be held securely in place.
Finally, adjust both sides of the bow to make it symmetrical and prepare to be the envy of your friends.
