INSTRUCTIONS: Determine whether the following symbolized arguments are valid or invalid by identifying the form of each. In some cases, the argument must be rewritten using double negation or commutativity before it has a named form. Those arguments without a specific name are invalid. ∼M M ⊃ ∼G G a. AC—invalid. b. DA—invalid. c. MT—valid. d. MP—valid. e. DS—invalid.

Determine whether each argument is valid or invalid. If it is valid, give a proof. If it is invalid, give an assignment of truth Values to the variables that makes the premises true and the conclusion false. $$\begin{array}{l}{p \rightarrow q} \\ {\sim p \rightarrow r} \\ {\frac{s \rightarrow \sim q}{\sim r \rightarrow \sim_{s}}}\end{array}$$

Analyzing Arguments and Proofs
Determine whether each argument is valid or invalid. If it is valid, give a proof. If it is invalid, give an assignment of truth Values to the variables that makes the premises true and the conclusion false. $$\begin{array}{l}{p \vee q} \\ {\sim p} \\ {\frac{r \rightarrow \sim q}{\sim r}}\end{array}$$
