I think that the answer to <em>"What could Mrs. Louis do next to be an effective participant in this discussion?"</em> is <em>"C"</em> or <em>"D"</em> which is......
<em>"C." "Move on to the next topic of conversation to keep the discussion on track
."</em>
<em>"D." "Challenge the validity of the report by questioning Mr. Hollembeak’s research methods."</em>
The correct answer is B. I took the test and D was wrong
It looks good.
You did a nice job being descriptive and your grammar looks fine.
