The manuscript is improved quite a lot, but still include new typo's and new careless mistakes as suggested below. Please don't count on reviewers as a proof-reader.

As already mentioned, the manuscript is improved quite a lot, but still includes new typo's and new careless mistakes. The explanation in the first half of the text is quite good while the last half is still not easy to understand. The last half is still more like a draft before proof-reading. Newly added parts of the text with red letters also include mistakes/redundancies/clearness. Although the paper could be improved by repeating review and re-edit procedure, it would be less likely to be done just one more additional time. So, the reviewer recommends the authors to dismiss it now and take a time to refine the paper.
