If (RvS) is true, which of the following is true of the truth values of statements R and S? (~ and v denote the logical operators NOT and OR, respectively.) O Both R and S must be false. Both R and S must be true. O R must be false, and S must be true. O R must be true, and S must be false.

### Logical Operators and Statement Analysis

**Question:**
If ~(R ∨ S) is true, which of the following is true of the truth values of statements \(R\) and \(S\)? (~ and ∨ denote the logical operators NOT and OR, respectively.)

**Options:**
1. \( \bigcirc \) Both \(R\) and \(S\) must be false.
2. \( \bigcirc \) Both \(R\) and \(S\) must be true.
3. \( \bigcirc \) \(R\) must be false, and \(S\) must be true.
4. \( \bigcirc \) \(R\) must be true, and \(S\) must be false.

### Explanation:
To solve this problem, we need to understand the logical expression \(~(R ∨ S)\). 

1. The symbol \( ∨ \) represents a logical OR, which means \(R ∨ S\) is true if either \(R\) is true, \(S\) is true, or both are true.
2. The symbol \( ~ \) represents a logical NOT, which negates the truth value of the expression it precedes.

Given that \( ~(R ∨ S) \) is true, it implies that \(R ∨ S\) is false. 

The expression \(R ∨ S\) is false only when both \(R\) and \(S\) are false. Therefore, the correct option is:

\( \bigcirc \) Both \(R\) and \(S\) must be false.
