You need to check if the object that is passed in is an instance of a string or a blogpost and return a string result accordingly. If the object is an instance of a string then you just need to cast the object to the result variable so that it is returned. If the object is an instance of a blogpost then you need to set the result variable to the blogposts title so that is returned.

  public static String getTitleFromObject(Object obj) {
    // Fix this result variable to be the correct string.
    String result = "";
    if(obj instanceof String) {
      result = (String) obj;
    } else if(obj instanceof BlogPost) {
      BlogPost bp = (BlogPost) obj;
      result = bp.getTitle();
    }
    return result;
  }
