Which of the following statement(s) is true a priori: 1) Some trees are oaks. 2) The oaks outside my window are trees. 3) The trees outside my window are oaks.

(2) The oaks outside my window are trees. An oak is a type of tree by definition. If all oaks are trees, then the oaks outside my window must be trees. In statement (1), there is nothing inherent in the definition of a tree to tell us that some trees are oaks. If oak trees were to go extinct, the basic definition of a "tree" would remain unaffected. We need more information to determine the truth of the statement. In statement (3), it is possible that the trees are oaks, but it is also possible that they are pines, willows, or any other type of tree. Nothing in the general definition of "tree" can tell us the species of the particular trees outside my window. We need more information to determine the truth of the statement.
