As a matter of stipulation, the act-set which would follow the act-set that terminates with ⟨voting for the language requirement⟩ at \(t_3\) is better than the act-set which would follow any other \(t_1\)–\(t_3\) act-set available to Jones at \(t_1\). So (G) implies that, at \(t_1\), Jones ought to do the best she can. However, (G) also implies that, at \(t_1\), Jones ought to ⟨stay home⟩ at \(t_1\) rather than ⟨go to the office⟩ at \(t_1\). This is because both acts are performable for Jones
