  Each of these principles seems quite plausible when considered in isolation. Principle (1) simply holds that an agent ought to perform the best option available to her. Assuming hedonistic act-utilitarianism, the best option(s) will be whichever one(s) maximize(s) hedonic utility. Principle (2) holds that if an agent is obligated to perform \(\langle A \rangle\) and her performing \(\langle A \rangle\) entails her performing \(\langle B \rangle\), then she is obligated to perform \(\langle B \rangle\). So, if an agent is obligated to ⟨drink a Coke⟩ and ⟨drinking a Coke⟩ entails ⟨drinking a soda⟩, then that agent is obligated to ⟨drink a soda⟩.
