Developers of neighborhood Y are trying to lure potential homebuyers by offering a large discount on newly built homes. As a result, the homes in neighborhood Y are available for 20% less than comparably sized homes in neighborhood X. So unless potential homebuyers distrust the developers of neighborhood Y, neighborhood X is unlikely to attract many homebuyers because there are plenty of houses available in neighborhood Y. Which of the following is an assumption on which the argument depends? ['The comparably priced homes in neighborhood X and neighborhood Y are all situated on similarly sized lots.', 'There are fewer houses for sale in neighborhood X than there are in neighborhood Y.', 'Neighborhood X does not have any qualities or features that would induce some homebuyers to pay higher prices for homes in neighborhood X.', 'None of the houses in neighborhood X are selling for less than the houses in neighborhood Y.']
