A coastal village in Norway began paying fishermen a small bonus for every worn-out net they brought back to the harbour instead of dumping it at sea. After the first year the scheme looked like a failure: the weight of recovered netting was far below the council's estimate of how much had previously been lost. However, that estimate had been based on the number of nets sold in local shops, and a later survey showed that many fishermen had been repairing old nets instead of buying new ones. When the council recalculated the figures using the survey, it found that the amount of netting lost at sea had fallen by almost a third.

- DThe scheme seemed to fail only because the figure used to judge it was misleading.

The text says the scheme looked like a failure because recovered netting was lower than the estimate of losses. It then explains that the estimate relied on net sales, which were misleading because many fishermen repaired old nets instead of buying new ones. After recalculation, losses at sea turned out to have fallen by almost a third. So the scheme only appeared to fail because of a flawed measure. The option about a larger bonus is wrong because no change in the bonus is mentioned. The option about fishermen stopping repairs reverses the facts, since repairing was the reason sales were low. The option about dishonest shops is unsupported, because nothing suggests that the sales figures were false, only that they were a poor basis for the estimate.
