Guard Schedule Surmise (Posted on 2022-08-28) Difficulty: 3 of 5
Art, Bob, Cab, and Ida are guards in a museum.

It is known that:
  1. Each of Art, Bob, and Cab stands guard on exactly four days every week.
  2. Exactly two persons stand guard together every day.
  3. No person stands guard three days in a row.
  4. Here is a partial listing that shows when they stand guard every week: +-----+-----+-----+ | Sun | Art | Bob | +-----+-----+-----+ | Mon | Cab | ? | +-----+-----+-----+ | Tues| Ida | ? | +-----+-----+-----+ | Wed | Art | ? | +-----+-----+-----+ |Thurs| Bob | ? | +-----+-----+-----+ | Fri | Cab | ? | +-----+-----+-----+ | Sat | Ida | ? | +-----+-----+-----+
Who does NOT stand guard with Ida?
