premise: A landscaper will plant exactly seven trees today—a hickory, a larch, a maple, an oak, a plum, a sycamore, and a walnut. Each tree must be planted on exactly one of three lots—1, 2, or 3—in conformity with the following requirements: The trees planted on one lot are the hickory, the oak, and exactly one other tree. The maple is not planted on the same lot as the walnut. Either the larch or the walnut, but not both, is planted on lot 1. Either the maple or the oak, but not both, is planted on lot 2. More trees are planted on lot 3 than on lot 1. Which one of the following is a complete and accurate list of the trees any of which could be planted on lot 1?
hypothesis: the hickory, the plum, the sycamore, the walnut
