摘要：
Several groups have claimed the discovery of intermediate-age globular clusters in M31 on the basis of low-resolution spectroscopy. We use high-resolution Keck spectra and HST imaging to show that three such objects have mass-to-light ratios like those of old Clusters, and thus are unlikely to be of intermediate age.
