Remember that the stronger conjugate acid has the weaker conjugate base. From the table of approximate pKa values given in this section, CH3SH (pKa ~ 10) is a stronger acid than CH3OH (pKa ~ 15) , so CH3O- is the stronger base.
Following the same reasoning and using the given approximate pKa values of the conjugate acids, ammonia (NH3) is a stronger base than acetate (CH2COO-), and hydroxide (OH-) is a stronger base than acetate.
