Advertisement: More gardeners in this county use Brackwell compost than use any other brand -- twice as many as the runner-up, according to the county horticultural society's survey of two thousand of its members last spring. The survey asked which brand members bought and did not ask what they thought of it. So Brackwell must be the best compost on sale in this county.

The reasoning above is most vulnerable to criticism on the grounds that it

Aassumes that the two thousand members surveyed named the brand they had bought rather than the one they felt they ought to name

Bassumes that the buying habits of this county's gardeners are representative of those of gardeners elsewhere

Cassumes that the county's gardeners all buy their compost by the bag rather than turning their own heaps, so that what the society's members named covers every gardener there is

Dconfuses being bought by the greatest number of gardeners with being used most heavily by those who buy it

Etakes the fact that more of the county's gardeners use one brand of compost than use any other to establish that that brand is the best on sale there
