Cutter: A peat block dries fit to burn only if it stands six weeks in the wind, and a block not fit to burn gives smoke and little heat. The wind failed here from the day we set our blocks out until we lifted them, so ours will burn badly. The co-operative's blocks came off the same bank as ours, so theirs will burn badly too.

Which one of the following most accurately describes a flaw in the cutter's reasoning?

AIt says nothing about how much peat the co-operative lifts off the bank in a season, so the quantity of bad fuel is nowhere fixed.

BIt moves from a block's not having dried as the cutter's rule requires to that block's burning badly, when a rule about what dries a block settles nothing about what it does on a fire.

CIt takes the two lots of blocks' having come off one bank to settle that they dried alike, when by the cutter's own rule what dries a block is the wind it stands in.

DIt concludes that the district's fuel will be poor from the wind's failing in one summer, treating a season's weather as the bank's usual weather.

EIt establishes the state of the co-operative's blocks by having a sample of them lifted and tried on a fire.
