This past year, Jack's Packaged Goods launched a yearlong advertising campaign for its packaged beef jerkies. At the end of the past calendar year, Jack's sold 5 million packs of beef jerkies compared to the 4 million sold during the previous year, an increase directly attributable to new customers brought in by the campaign. Profits from the additional sales, however, were substantially less than the cost of the advertising campaign. Clearly, therefore, the campaign did nothing to further Jack's economic interests.
Which of the following, if true, most seriously weakens the argument?
(A) Sales of packaged beef jerkies account for a relatively small percentage of Jack's Packaged Goods' profits.
(B) Most of the people who bought Jack's packaged beef jerkies for the first time as a result of the compaign were already loyal customers of other Jack's products.
(C) A less expensive advertising campaign would have brought in significantly fewer new customers for Jack's packaged beef jerkies than did the campaign Jack's Packaged Goods launched last year.
(D) Jack's made money on sales of packaged beef jerkies last year.
(E) In each of the past five years, there was a steep, industry-wide decline in sales of packaged beef jerkies.
