How does adding a parameter (1) in the RETURN_STRING function call resolve the issue in this scenario?

The issue in this scenario is that the function RETURN_STRING is defined to accept one parameter, but when calling the function, no parameter is provided. This results in a "missing argument" error. To resolve this issue, we need to ensure that when calling the RETURN_STRING function, we pass a parameter to it. 

// Define the RETURN_STRING function with one parameter
function RETURN_STRING($str) {
    return $str;
}

// Call the RETURN_STRING function with a parameter
echo RETURN_STRING("Hello, World!");
