TO BILL--------------
我对本题的理解是,
(D)in that their composition, tissues such as tooth and bone, is not normally found in the organ in which the tumor appears.
(E)in that they are composed of tissues such as tooth and bone, tissues not normally found in the organ in which the tumor appears.
即D项的意思为 their composition is not normally found in the organ in which the tumor appears.
而E项的意思为 tissues not normally found in the organ in which the tumor appears.
