1. The problem asks for the Boolean expression representing "4 greater than 5." 2. In mathematical terms, this is written as $4 > 5$. 3. Since 4 is not greater than 5, the expression $4 > 5$ is false. 4. In Boolean logic, false is represented as $\text{False}$. Therefore, the Boolean expression is $4 > 5$, which evaluates to $\text{False}$.
