You should wrap the two objects in another object for the View, commonly referred to as a "ViewModel".

public class QuestionAnswerViewModel
{
   public Question Question { get; set; }
   public ICollection<Answer> Answers { get; set; }
}

Bind to that in your View.

Then use something like AutoMapper to map it back to your two entities.
