Hi. I'm at 99% in completing the course. However, I was stuck at 2 questions. On of them is on Theme 3: Social Issues (Grammar & Vocabulary) Self Test Grammar. In the reading text, there are 10 words in bold but the answers that I must put in groups of lexical, grammatical and logical are only 9. I've tried every possible answer but failed. Is it due to the missing answer of the word self-regulation? Quick response is highly appreciated.
