Let us now take a closer look at the type of TOEIC questions that fell into the category
‘none of the above,’ since this proved to be the largest category in the second formatted
table (see Table 2). The information about the grammar applicable to these questions is,
simply, not explicitly put forth in the explanatory notes in the three textbook series
examined in this study. So, the question is: How, then, can students acquire this level of
knowledge about English grammar?
