Last week’s discussion emphasized that to achieve truly good writing in English, we should aim for parallelism every time we make statements that present several grammar elements in a series. Elements alike in function should all have the same grammar pattern. Using this parallelism rule, in particular, an article or preposition that applies to each of all the serial elements in a sentence must either be used only once before the first serial element, or else used again before every serial element.
