public President(String name, int start, int end) {
this.name = name;
this.start = start;
this.end = end;
}
...
}

method follows. We use type dependencies again to ex-

string is passed to the
getOrder
method, which returns the ordinal as an integer. We add
1 to it since the list of presidents also started at one:
public void processWhoQuestion(List<TypedDependency> tdl) {
List<President> list = createPresidentList();
for (TypedDependency dependency : tdl) {
if ("president".equalsIgnoreCase(
