I'm putting my comments about your TIAS here since you didn't allow for comments on the actual TIAS posting. I think you have a mistake here in your issue. You say that because of technology, there is no real need for cattle for food anymore. How can that be? Have we suddenly stopped eating meat? I think what you meant to say was that the role of the cowboy has diminished because of technology, not the need for cattle for food because we definitely still use cattle for food. Because of this I have to give you a 3.6 or an A-. Make sure to proof your work.
