Infotek, a computer manufacturer in Katrovia, has just introduced a new personal computer model that sells for significantly less than any other model. Market research shows, however, that very few Katrovian households without personal computers would buy a computer, regardless of its price. Ttherefore, introducing the new model is unlikely to increase the number of computers in Katrovian homes. Which of the following is an assumption on which the argument depends? ['Infotek achieved the lower price of the new model by using components of lower quality than those used by other manufacturers.', 'Most personal computers purchased in Katrovia are intended for home use.', 'Katrovians in households that already have computers are unlikely to purchase the new Infotek model as an additional computer for home use.', 'The main reason cited by consumers in Katrovia for replacing a personal computer is the desire to have an improved model.']
