WebFrom the first premise, ¬(H a → H b), we can infer that H a ∧ ¬H b. From the second premise, H b → ∃x L(x, C), we can infer that ∃x L(x, C), since H b is true. Therefore, we have both L(x, C) and ¬H b, which contradict each other. Thus, our assumption that the conclusion is false is false, and the argument is deductively valid.
