**Exercise 6.**
Construct a truth table for the following statement:

\((p \lor \sim q) \rightarrow q\)

---

To solve this, start by considering the logical operators involved:

1. **Disjunction (\(\lor\))**: This operator is true if at least one of the operands is true.
2. **Negation (\(\sim\))**: This operator inverts the truth value of its operand.
3. **Implication (\(\rightarrow\))**: This operator is false only when the first operand is true and the second operand is false.

The truth table will examine all possible truth values of \(p\) and \(q\):

| \(p\) | \(q\) | \(\sim q\) | \(p \lor \sim q\) | \((p \lor \sim q) \rightarrow q\) |
|-------|-----|------|-----------------|-------------------------|
| T     | T   | F    | T               | T                       |
| T     | F   | T    | T               | F                       |
| F     | T   | F    | F               | T                       |
| F     | F   | T    | T               | F                       |

Explanation of each column:
- **\(p\) and \(q\)**: Initial truth values we are considering.
- **\(\sim q\)**: The negation of \(q\).
- **\(p \lor \sim q\)**: The result of the disjunction between \(p\) and \(\sim q\).
- **\((p \lor \sim q) \rightarrow q\)**: The final implication we want to evaluate.

This table effectively illustrates both the intermediate logical outcomes and the final conclusion of the statement for all possible logical inputs.
