Mr. Zhang packed the four treasures of the study in a cabinet with four drawers, and asked the students to guess which layer was pen, ink, paper, and cymbals. According to the order of pen, ink, paper, and cymbals, Xiao Li guessed the four treasures in order. On the first, second, third, and fourth floors, Xiao Wang guessed that the four treasures were installed on the first, third, fourth, and second layers in turn, and Xiao Zhao guessed that the four treasures were installed on the fourth, third, first, and second in order. Xiao Yang guessed that the four treasures were installed in the fourth, second, third, and first layers in turn. Teacher Zhang said that Xiao Zhao did not guess one, Xiao Li and Xiao Wang each guessed one, and Xiao Yang Guessed two correctly. It can be inferred from this:. ['The first drawer is filled with ink.', 'Paper is in the second drawer.', 'The pen is not in the third drawer.', 'It ’s not in the fourth drawer.']
