Property taxes are typically set at a flat rate per $ 1,000 of officially assessed value. Reassessments should be frequent in order to remove distortions that arise when property values change at differential rates. In practice, however, reassessments typically occur when they benefit the government – that is, when their effect is to increase total tax revenue. If the statements above are true, which of the following describes a situation in which a reassessment should occur but is unlikely to do so? (a) Property values have risen sharply and uniformly. (b) Property values have all risen – some very sharply, some less so. (c) Property values have for the most part risen sharply yet some have dropped slightly. (d) Property values have for the most part dropped significantly; yet some have risen slightly. (D) (e) Property values have dropped significantly and uniformly. 答案选D,给的解释是1. should occur,即property values change at different rates 2. unlikely to occur,即when reassessment does not benefit government。第二点我就觉得D不对了,既然要unlikely to occur,就要是effect is to decrease,那D选项后面半句是some have risen slightly.不管增长什么速度它还是在增长啊,可是C选项就不一样,后半句是drop,那就使effct is to decrease,那么reassessment is unlikely to occur.所以我觉得选C,能否帮我解释一下。
