Does the connection between 'I recently purchased a new computer, and, because it operated on a system different from the one of my old computer, I asked a few friends to recommend a word-processing package that I might.find useful.' and 'I already knew how to use the OS that my new machine runs.' lack any definitive logical relationship?
