premise: In one week—Monday through Friday—a library's bookmobile will visit five of the following six neighborhoods—Hidden Hills, Lakeville, Nottingham, Oldtown, Park Plaza, and Sunnyside. Exactly one neighborhood will be visited on each of the five days, and none of the neighborhoods will be visited on more than one day. The bookmobile's schedule must conform to the following conditions: Hidden Hills is visited, but not on Friday. If Oldtown is visited, then it is visited on the day immediately before Hidden Hills is visited. If Lakeville is visited, then it is visited on Wednesday. Nottingham and Sunnyside are both visited, but not on consecutive days. If Nottingham is visited on Thursday, which one of the following must be true?
hypothesis: Hidden Hills is visited on Wednesday.
