Previously, Autoco designed all of its cars itself and then contracted with specialized parts suppliers to build parts according to its specifications. Now it plans to include its suppliers in designing the parts they are to build. Since many parts suppliers have more designers with specialized experience than Autoco has, Autoco expects this shift to reduce the overall time and cost of the design of its next new car. Which of the following, if true, most strongly supports Autoco's expectation? ['When suppliers provide their own designs, Autoco often needs to modify its overall design.', 'When suppliers built parts according to specifications provided by Autoco, the suppliers competed to win contracts.', 'In order to provide designs for Autoco, several of the parts suppliers will have to add to their existing staffs of designers.', "Most of Autoco's suppliers have on hand a wide range of previously prepared parts designs that can readily be modified for a new car."]
