Identify the determining dimension or dimensions that explain why you bought the specific brand you did in your most recent purchase of a (a) soft drink, (b) shampoo, (c) shirt or blouse, and (d) larger, more expensive item, such as a bicycle, camera, or boat.

Try to express the determining dimension(s) in terms of your own personal characteristics rather than the product's characteristics. Estimate what share of the market would probably be motivated by the same determining dimension(s).
