How do you ensure that both booleans are true?

I don't understand how to make both booleans true.

Hey Lauren,

The question is referring to the logical operators of Java (And/Or). In this particular case, you'll want to use the logical And operator, which is written as '&&'. 

boolean shouldContinue = isRefreshed && isReadyToGetStarted;

But try to wrap your head around why this works instead of using the logical Or operator. I'd suggest going over this section of the course again before proceeding.

Best,

Jacob
