Dear authors:
Thank you for uploading the revised manuscript. I studied it with the open discussion and concluded that the manuscript was substantially improved. The manuscript structure was well reorganized, such that introductory sections were shortened and a new section on limitations was added. Several figures (e.g., Figure 4) were also refined, improving the presentation of the study. Finally, considering the reviewers' evaluations, I recommend that the manuscript be accepted for publication.
