Write the following statement in the form of "if-then":
To get an $A^{+}$ in the class,it is necessary that you do all the exercises of the book.

The dual of the statement pattern $(p \wedge \sim q) \to (q \wedge \sim p)$ is equivalent to

The contrapositive of the inverse of $p$ $\rightarrow (p$ $\rightarrow q)$ is

The correct simplified circuit diagram for the logical statement $[\{q \wedge (\sim q \vee r)\} \wedge \{\sim p \vee (p \wedge \sim r)\}] \vee (p \wedge r)$ where $p, q, r$ represent switches $S_1, S_2, S_3$ respectively.

The statement pattern $(p \lor q) \to \sim r$ is logically equivalent to

Write the converse of the following statement:
If you do all the exercises in the book,you get an $A$ grade in the class.
