Conclusion: 3 manufacturers, who control 80 percent of the laundry detergent market will bring about the virtual disappearance of old-style bulky detergents.
Premise: The concentrated detergents will be sold in smaller packages to reduce cardboard packaging and other production costs.
If other manufacturers follow the suit and consumers are indifferent or inclined to buy the smaller packaged detergent then there is a possibility of disappearance of old-style bulky detergents.
This is Strengthening the argument question..let's go through the options.
(A) Most smaller manufacturers of laundry detergents will consider it too expensive to retool factories for the production of the smaller detergent packages.......
Smaller manufacturers control 20% of the market they will still be producing bulky detergents. This is weakening the argument instead of strengthening it. (B) Many consumers will be skeptical initially that the recommended small amount of concentrated detergent will clean laundry as effectively as the larger amount of the old-style detergent did.....
Because of this skepticism, they may not buy the smaller packaged detergent. But to bring the change, consumers should adopt the change. Not strengthening. (C) 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............
This also in a way is not strengthening the argument. If costs are high then it would not be easy to bring adoption.(D) 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.......
Irrelevant (E) Consumers are increasingly being persuaded by environmental concerns to buy concentrated detergents when available in order to reduce cardboard waste..............
This may drive adoption among consumers. This is in line with our thinking.
IMO correct option should be E.
