How to get record from query using AggregateResult

Question

I am trying to get the record from query from below soql query. I am getting "Variable does not exist: Question__c"

Below is my code

public pagereference loginflowsexornot()
{        
    List<AggregateResult> ratobj1 = [SELECT Question__c,Order_Sequence__c FROM Rating_Request__c where User__c=:UserInfo.getUserId() and User_Rating__c = 0 group by Question__c,Order_Sequence__c order by Order_Sequence__c  LIMIT 1];
    
    System.debug('Get user Id is : ' + UserInfo.getUserId());
    System.debug('Query Count size is : '+ ratobj1.size());
    System.debug('Get the Question is :' + ratobj1.Question__c);
    
    if (ratobj1.size() == 0)
    {
         return Auth.SessionManagement.FinishLoginflow('/');
    }
    else
    {
         return null;    
    }
}

Can anyone help or suggest how to get record.
