Policy adviser: The front-of-pack label was introduced two years ago to work on manufacturers rather than on shoppers, and shoppers' buying habits have indeed hardly shifted. More than two hundred products have since been reformulated by their makers to carry a green mark instead of an amber one. On the manufacturer the label has worked.

Which one of the following, if true, most seriously weakens the adviser's argument?

ANearly all the products reformulated in the two years had already been promised by their makers under a trade agreement reached well before the label was proposed.

BShoppers shown the two marks side by side in a hall test could say correctly which product carried which, whichever way round they came, and most said they would look for green.

CThe products reformulated in the two years are almost all lines sold in small quantities, the leading brand in each category having kept its amber mark.

DAmber-marked products make up a smaller share of the labelled range than two years ago, chiefly because the range has grown to take in many new lines.

EReformulating a product so that it leaves the amber band usually takes a maker between one and two years.
