#### ARGUMENT FIVE
- **Validity Check**: [Valid □ / Invalid □]
1. \( A \lor B \)
2. \(\therefore A \cdot B\)
---
#### ARGUMENT SIX
- **Validity Check**: [Valid □ / Invalid □]
1. \(\sim C\)
2. \(\therefore \sim (C \lor A)\)
---
#### ARGUMENT SEVEN
- **Validity Check**: [Valid □ / Invalid □]
1. \( R \cdot (T \lor S) \)
2. \( T \)
3. \(\therefore \sim S\)
---
### Explanation:
Each argument consists of premises followed by a conclusion indicated by the symbol \(\therefore\). The task is to evaluate whether the conclusion logically follows from the premises, checking the appropriate box to indicate validity or invalidity. Each argument may employ different logical connectives, such as conjunction (\(\cdot\)), disjunction (\(\lor\)), and negation (\(\sim\)).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa2f3a067-2abe-4372-becf-a6d5e24db871%2F7cdcc266-5aad-46af-9a6f-e725de80b9b2%2Fq9lgp97_processed.png&w=3840&q=75)
