Wh-moved NP complement

Wh-questions can be formed on every NP object or indirect object that appears in the declarative tree or in the passive trees, as seen in sentences ((196))-((201)). A tree family will contain one tree for each of these possible NP complement positions. Figure 14.3 shows the two extraction trees from the ditransitive tree family for the extraction of the direct (Figure 14.3(a)) and indirect object (Figure 14.3(b)).
