Wh-moved Adjective complement

In subcategorizations that select an adjective complement, that complement can be questioned in a wh-question, as in sentence ((156)).

The tree families with adjective complements include trees for such adjective extractions that are very similar to the wh-extraction trees for other categories of complements. The adjective position in the VP is filled by an $\epsilon$ and the trace feature of the adjective complement and of the adjective daughter of S_q are co-indexed. The extracted adjective is required to be <wh>=+^13.2, so no topicalizations are allowed. An example of this type of tree is shown in Figure 13.6.
