In this paper, we study the singularities of a general hyperplane section of a three-dimensional quasi-projective variety over an algebraically closed field of characteristic 0]]>. We prove that if has only canonical singularities, then has only rational double points. We also prove, under the assumption that 5]]>, that if has only klt singularities, then so does.
