Question
### Determining Logical Statements using Truth Tables

#### Problem Statement:
Use a truth table to determine whether the statement is a tautology, a self-contradiction, or neither.

The statement to evaluate:  
\[ (\neg p \land \neg q) \land (p \lor q) \]

#### Truth Table:

Complete the truth table.

| p | q | \neg p \land \neg q | p \lor q | (\neg p \land \neg q) \land (p \lor q) |
|---|---|--------------------|----------|---------------------------------------|
| T | T |                    |          |                                       |
| T | F |                    |          |                                       |
| F | T |                    |          |                                       |
