Change
                     

select m);

To

 using (var _db = new Model1Container())
        {
            var a = (from m in _db.Answers
                     where m.QuestionQId == id
                     select m).ToList();

            return View(a);
        }

To force execution now. Otherwise execution of the query can happen outside the scope of your _db variable.
