Unless the residents of Glen Hills band together, the proposal to rezone that city will be approved. If it is, the city will be able to build the water and sewer systems that developers need in order to construct apartment houses there. These buildings would attract new residents, and the increased population would probably result in overcrowded schools and would certainly result in roads so congested that new roads would be built. Neither new roads nor additional schools could be built without substantial tax increases for the residents of Glen Hills. Ultimately, this growth might even destroy the rural atmosphere that makes Glen Hills so attractive. Which one of the following can be properly concluded from the passage? ['If developers build apartment houses in Glen Hills, there will be substantial tax increases for the residents of Glen Hills.', 'If the rezoning proposal does not pass, the rural atmosphere in Glen Hills will not be lost.', 'If developers do not build apartment houses in Glen Hills, the schools of Glen Hills will not be overcrowded and roads will not be congested.', 'If developers do not build apartment houses in Glen Hills, the taxes of the residents of Glen Hills will not increase substantially.']
