• Which is the sound way to analyze a conditional proposition?
• Every affirmative connective conditional requires its antecedent to be actually true.
• A coincidental connective need not have an essential or causal entailment between its clauses.
• In a genuine disjunction both alternatives may be false, but they cannot both be true.
• In an exclusion-of-omission disjunction, both alternatives may be true.
