Query: Sudden Singularities in Brans-Dicke Cosmology and its Generalisations   We show that cosmological sudden singularities that respect the energy
conditions can occur at finite times in Brans-Dicke and more general
scalar-tensor theories of gravity. We construct these explicitly in the
Friedmann universes. Higher-order versions of these singularities are also
possible, including those that arise with when scalar fields have a
self-interaction potential of power-law form.7 pages, no figures
