premise: Each day of a five-day workweek (Monday through Friday), Anastasia parks for the entire day in exactly one of three downtown parking lots—X, Y, and Z. One of the lots costs $10 for the day, another costs $12, and the other costs $15. Anastasia parks in each of the three lots at least once during her workweek. The following conditions must apply: On Thursday, Anastasia parks in the $15 lot. Lot X costs more than lot Z. The lot Anastasia parks in on Wednesday costs more than the one she parks in on Friday. Anastasia parks in lot Z on more days of the workweek than she parks in lot X. Which one of the following could be a complete and accurate list of which lot Anastasia parks in each day, listed in order from Monday through Friday?
hypothesis: Z, Z, X, X, Y
