Where the wind blows from one quarter most of the year, a coastal dune takes the barchan form. On the Skerne coast, where the sand is coarse and the supply steady, the wind does not. So the Skerne dunes do not take the barchan form.

The flawed reasoning above is most similar to that in which one of the following?

AWhere a kiln is fired above eleven hundred degrees, the glaze on a pot crazes. The Ashwell kiln, a small updraught one, does not fire so high. So its glaze does not craze.

BA dune is parabolic only where its arms point upwind, and the Brannock dunes' arms point downwind. So they cannot be parabolic.

CWhere a hedge is cut every second year it thickens at the base, and most but not all the Corran Lane hedges are so cut. So every hedge there has thickened.

DWhere a tidal race scours a foreshore, no shingle gathers on it. No shingle has gathered on the Dunmail foreshore, which lies behind a spit. So Dunmail is not one the races pass by.

EEvery dune surveyed in 1930 was resurveyed in 1970, and the Elsted dune was not. So it was not surveyed in 1930.
