Ginger proofreads sentences with faulty punctuation

We fed Ginger some sentences with common punctuation mistakes: chiefly, run-on or fused sentences (ROS), comma splice cases (CS), and sentence fragments (SF).

There is no need to add another article, and adding it would disrupt the sentence balance:



Text used in the experiment: the sentences were devised to test student knowledge on common syntax and punctuation mistakes by the convenor of an undergraduate writing course at Auckland University.
