Robyn: A new line of designer imposter cosmetics could be very successful in certain markets. Manufacturers developing a new line of designer imposter cosmetics should focus on matching the packaging of the new line as closely as possible to the name brand cosmetic because the packaging is a significant part of brand recognition. Linda: Packaging is a significant part of brand recognition, but it is not the most important aspect. Generic food brands whose packaging closely resembles the name brand versions are not successful at luring the name brand' s customers unless the quality of the product is the same. Ttherefore, manufacturers that want to develop a successful line of designer imposter cosmetics should focus more on creating a product that is similar in quality to the original rather than focusing their energies on the packaging in an attempt to take advantage of brand recognition. The claim that generic food brands whose packaging closely resembles the name brand versions are not successful at luring the name brand products' customers unless the quality of the product is the same plays which one of the following roles in Linda's argument? ['It provides background information related to manufacturing generic cosmetic lines.', 'It provides a specific example that illustrates her general claim.', 'It is a secondary conclusion used to support the main conclusion.', 'It is the main conclusion of her argument.']
