Three major laundry detergent manufacturers have concentrated their powdered detergents by reducing the proportion of inactive ingredients in the detergent formulas. The concentrated detergents will be sold in smaller packages. In explaining the change, the manufacturers cited the desire to reduce cardboard packaging and other production costs. Market analysts predict that the decision of these three manufacturers, who control 80 percent of the laundry detergent market, will eventually bring about the virtual disappearance of old-style bulky detergents. Which one of the following, if true, most strongly supports the prediction made by the market analysts? ['Most smaller manufacturers of laundry detergents will consider it too expensive to retool factories for the production of the smaller detergent packages.', 'Some analysts believe that consumers will have to pay a greater cost per load of laundry to use the new concentrated detergent than they did to use the old-style detergent.', 'Consumers are increasingly being persuaded by environmental concerns to buy concentrated detergents when available in order to reduce cardboard waste.', 'Major supermarkets have announced that they will not charge the detergent manufacturers less to display their detergents, even though the detergents will take up less shelf space.']
