A conditional sentence with a false antecedent is always

true
false
Cannot be determined
not a sentence

i believe it is true but unsure Please help me

cannot be determined

Take an example:

if it's raining, I carry an umbrella.

tells me nothing about whether I carry an umbrella when it's not raining.

To determine the truth value of a conditional sentence with a false antecedent, we need to understand the structure of a conditional statement. A conditional statement is usually written in the form "If P, then Q," where P is the antecedent (the condition) and Q is the consequent (the result).

When the antecedent of a conditional sentence is false, it means that the condition being described in the sentence is not satisfied. In this case, there are two possibilities for the truth value of the conditional sentence:

1. If the consequent (Q) is true regardless of the antecedent (P), then the conditional sentence is considered true.
2. If the consequent (Q) depends on the antecedent (P) being true, then the conditional sentence is considered false.

In your case, since the antecedent is false, it means that the condition described in the sentence is not satisfied. Therefore, the conditional sentence is considered true because the truth value of the consequent does not depend on the truth value of the antecedent.

So, in summary, a conditional sentence with a false antecedent is always true.
