If A is a finitely generated torsion module, then {re RI rA = OI is a nonzero

Question:

If A is a finitely generated torsion module, then {re RI rA = OI is a nonzero ideal in R, say (r1). r1 is called the minimal annihilator of A. Let A be a finite abelian group with minimal annihilator m e Z. Show that a cyclic subgroup of A of order properly dividing m need not be a direct summand of A.
