   After a long time trying to solve this, I think that I may have the answer: C   
      
   Why? This is more of a Logic problem than Reading Comprehension.   
   We are assuming that we are only using 1 diagram, but in this case we know   
   that because XYZ and XWZ are both true, we have an option of two diagrams:   
      
   Diagram 1: XYWZ   
   Diagram 2: XWYZ   
      
   we need to figure out which of the following solutions is true:   
   A. XWY   
   B. XYW   
   C. ZWX   
   D. ZWY   
   E. None of the Above   
      
   Let's compare the solutions for each diagram:   
      
   A. XWY - Diagram 1 (False)/ Diagram 2 (True)   
   B. XYW - Diagram 1 (True) / Diagram 2 (False)   
   C. ZWX - Diagram 1 (True) / Diagram 2 (True)   
   D. ZWY - Diagram 1 (True) / Diagram 2 (False)   
      
   Only 1 answer is true for BOTH diagrams which is answer C.   
   I am only assuming that this is correct and that they want us to choose which   
   answer works best for both diagrams since there are two possible diagrams to   
   work with and we do not know which one we should use.   
   Hope this helps.
