Restorer: The Ashby tide mill grinds two hours on each ebb, where its eighteenth-century daybooks record four. The gate the trust fitted, made from the mill's drawings, passes more water than the wheel can take. The pond was dredged out to its old bed before the wheel was rehung, yet fills to forty centimetres below the old sill mark. So the short grinding day is at least partly a matter of how little the pond holds.

Which one of the following, if true, most strengthens the restorer's argument?

AThe gate the trust fitted cannot be shortening the grinding day, since a gate that passes more water than the wheel can take is not what limits it.

BThe river-driven mills on this estuary grind today for as long as their own accounts record, none of them holding water behind a tidal sill.

COn the four ebbs since a temporary cut let the pond fill to the old sill mark, the mill ground over three hours each time, with gate and wheel untouched.

DThe daybooks counted the grinding day from the hour the miller opened the gate, and a miller then counted into it the wait for the tide outside to fall far enough to turn the wheel.

ERestoring a tide mill is reckoned more a matter of water than machinery, and the trust has always thought so.
