okey, said donovan. let's check what we know. one: the DV-5 passed every test when in was in the factory at U.S. robots. two: U.S. robots said that the master robot-and all the sub-robots-would pass the tests, when they started working on an asteroid. three: the robots are not passing the tests here. four: if they don't pass all the tests, U.S. robots will lose a lot of money. five: if we can't explain why the robots are failing the tests, we'll be in trouble.
