Query: On the ghost issue of extended quasidilaton   We report on our independent investigations of the puzzle of cosmological
perturbations in extended quasidilaton. We confirm the claims of presence of
the Boulware-Deser ghost. We use both the language of cosmological
perturbations with broken diffeomorphisms and the Stuckelberg approach.
