The conditional does not have the effect of a conditional but the consequent clause.
the (global) SI from the use of some in the consequent clause affects the current information state directly and has the effect of a global SI: (30) s + "you want to have some apples" = s s + "If you want to, you may have some apples" = s\((s+"you want to have some apples")\(s+ "you want to have some apples"+"you may have some apples")) = s\(s\(s+"you may have some apples")) = s+"you may have some apples" As shown above, the conditional has the same meaning as the consequent clause, which makes a SI from the consequent clause a global effect on the current information state.
