While this counterexamp! le satisfies the conditions of the D-N model it explains a cause using the effect rather than explaining the effect by means of the cause. This lack of account for causal influences makes this D-N argument assert into the realm of inaccuracy. Another problem that arises with the D-N model is when all four adequacy conditions can be satisfied but the explanation is clearly not a scientific explanation.
