Abstract: Necessary and sufficient conditions are given that all solutions of ${y^{(n)}} + f(t, y) = 0$ which are continuable to infinity are oscillatory in the case $n$ is even and are oscillatory or strongly monotone in the case $n$ is odd. The results generalize to arbitrary $n$ recent results of J. Macki and J. S. W. Wong for the case $n = 2$ and include as special cases results of I. Kiguradze, I. Ličko and M. Švec, and Š. Belohorec.
