### Logic and Truth Tables

**Problem 5: Creating a Truth Table**

Suppose you wish to create a truth table to analyze an argument whose variables are: \( A, B, C, R, S, Q \). How many rows do you have to create to make a truth table?

**Problem 6: Logical Equivalence**

Create a truth table to determine whether the following symbolic statements are logically equivalent:

1. \(\sim ((P \land Q) \lor S)\)
2. \((\sim P \lor Q) \land \sim S\)

---

### Explanation:

**Problem 5** involves determining the number of rows in a truth table based on the number of variables. For a set of \( n \) variables, a truth table contains \( 2^n \) rows to account for all possible combinations of truth values (True or False) for each variable.

**Problem 6** requires constructing a truth table to compare two logical expressions and check for logical equivalence. This involves evaluating both expressions for each possible combination of truth values of the variables \( P \), \( Q \), and \( S \), and comparing their outcomes. If the columns of truth values for both expressions are the same in every row, the expressions are logically equivalent.
