Highlight key findings, not RQs, in boxes

Reviewer B:
Also, the paper presentation shall be further improved. For example, the paper organization can be further improved by just talking about all the RQs and their motivations first, and then presenting the result analysis for all of them. It is also strange to highlight RQs in boxes; it is more common and useful to highlight key findings in boxes.

Reviewers A and C, on the other hand, finds our paper to be easy-to-follow.

I do agree, however, that we should highlight key findings in boxes, rather than RQs.
