Term matching

Drag the keywords below and drop them into the empty rectangles so that each time a pair of matching terms are formed. Click the check button to see if you did it correctly. The reset button sets all the terms back to their original position.
Hint: The terms in this exercise are used in the way they were introduced in this lesson. Literature is likely to use these terms slightly differently.

3-Scheme-Architecture

Drag the blue numbers near the keywords onto the correct white circles in the graphic. Click the check button to see if you did it correctly. The reset button sets all the numbers back to their original position.
Hint: The check button only works correctly after covering all of the empty circles in the graphic with a number.
