How about 'The boy learns theorems about geometry from a textbook by 
repetition.'

Le (boy) cu cilre le (theorems) le (geometry) le (textbook) le nu (repeat).

Here the x2 and x3 aren't mutually exclusive.  In fact, it seems to me that 
x2 will always be a subset of x3, although I'm not sure why the "du'u" is 
there. 
(I guess a dictionary would help too.)
