Abstract: The paper is devoted to an oscillation theorem for the second-order forced linear differential equation of the form . The sign of the coefficient is not definite, and the function is not necessarily the second derivative of an oscillatory function. The question raised by J. Wong in *Second order nonlinear forced oscillations* (SIAM J. Math. Anal. **19** (1988), 667-675) is answered. A region of oscillation of Mathieu's equation is specified.
