Angga, I notice many improvements of your writing in compare to previous essays, particularly in terms of your essay-organization. The idea that you deliver is also very informative and clear. Yet, you still need more improvements in your grammar, especially when it comes to singular and plural issues, and you still make one mistake about your spelling, which I think it is unnecessary if you are more aware about that. Another suggestion for you is that, you need to state clearly that "the benefits are able to outweigh the drawbacks" to avoid misleading, because examiner is not a mind-reader. Lastly, for a detailed corrections of your grammatical issues, with corrections applied.
