I have attached the article for reference. There are several questions to be answered for this paper but I am stuck on the following.
1) Attempt to give another interpretation of the results. Don’t agree with the author's results.
2) Propose a significant and feasible follow up experiment using essentially the same methods employed by the authors that might decide between the your interpretations and the author's interpretations.
3) What new ideas did you learn from reading this paper?
