Van wie heeft u een foto op uw boksbal hangen? Extraction from NPs in Dutch

This paper presents arguments from a corpus study that confirm the claim by Jack Hoeksema that extraction from PPs and subjects is possible in Dutch. Hoeksema presents data involving relative clauses. but we show that similar cases can be found in WH-questions as well. The suggestion that these are restricted to PP-arguments of a noun is problematic, however, as there are no clear tests for distinguishing PP-arguments of a noun from PP-adjuncts.
