A conditional is false when both premise and conclusion are false. O C. A predicate is a proposition-valued function. O D. It is possible to define disjunction using only negations and conjunction. O E. Domain-restricted universal quantification is logically equivalent to the unrestricted universal quantification of a conditional. OF. The negation of a conjunction is the disjunction of the negations. OG. (p - q) A (p -+ -q) is a contradiction. OH. Inverse and converse are logically equivalent. OI. (p - q) V (p - -q) is a tautology. OJ. The contrapositive is the inverse of the converse
