1. The problem is to determine the correct way to write the constructor for the subclass \texttt{EnglishWords} that extends \texttt{Words}. 2. The superclass \texttt{Words} has a constructor \texttt{Words(String w)} which initializes \texttt{myWord}. 3. In Java, when a subclass constructor calls a superclass constructor, the call to \texttt{super(...)} must be the first statement. 4. The subclass \texttt{EnglishWords} has two fields: \texttt{myWord} and \texttt{myVowels}. We want to initialize \texttt{myVowels} to an empty string "". 5. Therefore, the correct constructor body must first call \texttt{super(w);} and then initialize \texttt{myVowels = "";}. 6. The option that matches this is: ```java super(w); myVowels = ""; ``` 7. The other options are incorrect because: - \texttt{myVowels = ""; super(w);} is invalid since \texttt{super(w);} must be first. - \texttt{super(w); myVowels = AEIOU;} is invalid because \texttt{AEIOU} is not a string literal (missing quotes). Final answer: \texttt{super(w); myVowels = "";}
