        return null;
        //PageReference myPage = Page.

    }
}

Answer 1

You can simply access it just like any other variable. I'm assuming that since you have a list of your custom items you would put it in some sort of repeat or pageBlockTable.

<apex:repeat value="{!offeringData}" var="data">
  <apex:outputField value="{!data.Id}" /><br/>
</<apex:repeat>

EDIT: Since your custom object looks up to Question, you need to actually have a list of your custom object and not just a single one.

public Offering_Details__c offeringData {get;set;} -> public List<Offering_Details__c> offeringData {get;set;}

EDIT 2:

//I don't know the actually lookup field since you didn't give this information but you should be able to figure it out.
offeringData = [SELECT Id FROM Offering_Details__c WHERE QuestionId = :offeringId];
