premise: Tracy's Flower Shop delivers exactly six types of flowers—lilacs, magnolias, orchids, roses, tulips, and violets. Exactly six deliveries are made over a period of two consecutive days—Friday and Saturday. Three deliveries are made each day, at three different times each day—10 A.M., 2 P.M., and 4 P.M. Each of the six deliveries involves only one of the six types of flowers. The deliveries are made in accord with the following: The violets are delivered on Friday. The lilacs are delivered at some time before the tulips. The violets are delivered at some time before the magnolias. The orchids and the roses are delivered on the same day as one another. If the magnolias and the orchids are delivered on the same day, then which one of the following could be true?
hypothesis: The violets are delivered before the lilacs.
