Fleas<br>My dog has fleas and constantly scratching himself. I took my dog to the veterinarian office. The veterinarian gave my dog two shots. Eventually the fleas started to die. My dog finally stop scratching himself.
The word "veterinarian" contains the letter "g". 
My statement is definitely incorrect because the word "veterinarian" does not contain a "g", as is clearly demonstrable by looking at the letters in the word. I think the system had difficulty because it probably computes whole terms and statement patterns along with possible synonyms, without accounting for any language rules that have to do with the construction of the words themselves. 
( z1 contain :ARG0 ( z2 word :mod ( z3 vegetarian ) ) :ARG1 ( z4 letter :mod "g" ) )
