The following task should allow you to test if you have understood the content of this lesson.
Drag the numbers beside the terms onto the circles in the graphic. Place them as
exactly as possible and click '>Check' when you have placed them all. Symbols
will show you which numbers are placed correctly and which are on the wrong place. The
'>Reset' button clears the graphic from all numbers.
Attention: The
'>Check' button only works correctly if all circles in the graphic are covered
with a number.
