JavaScript JavaScript Basics (Retired) Making Decisions with Conditional Statements Add a Final Else Clause

I'm not quite understanding how to use two different variables in one else clause.

I'm supposed to add a final else clause to check if both variables are false. I've tried multiple solutions I've found on the Internet, but none of them pass the quiz. Please help.

script.js
var isAdmin = false;
var isStudent = false;

if ( isAdmin ) {
    alert('Welcome administrator');
} else if (isStudent) {
    alert('Welcome student');
} else if (isAdmin == false) {
    alert('Who are you?');
} else (isStudent == false) {
    alert('Who are you?');
}

An else doesnt take a condition. It's a fallback if none of the 'if' or 'else if' branches evaluate to true.
