We now make several observations:
Mr. Bennington’s horse must be Helene because the other four names are already assigned in the horse column.
Mr. X cannot be Col. Cunningham, as the latter is married to Helene whereas Mr.X is married to Georgette.
Hence, since Col. Cunningham owns Jasmine and Mr.X owns Y,Y cannot be Jasmine.
Nor can Y be Francine or Helene, since Y is married to Mr. Bennington, and Francine and Helene are not.
Y cannot be Georgette, since Georgette’s husband owns Y , according to clue 8.
The only possibility remaining is that Y is Inez. But then Mr. X must be Mr. Elmsby (since he owns Inez).
We can now consolidate our chart to obtain Figure 1.9. By the process of elimination, we have discovered that Jasmine is married to Durwood Dunstan.
