Hii... lightfox thank you for scrutinize my work. I am little bit confuse to start my second body paragraph. Let me explain on why I put "on the other hand". I would like to make transition to make another idea. Particularly, I would like to start the counter fact providing in prompt about internet as the source of information.
By this way, you give a good solution on putting "Also". Thank you
Other disadvantages could be the lack if reliability (i.e. Wikipedia) and security (i.e. hackers).
Juan, Yap, in the beginning I made my mind map, I also consider to do as your suggestion, but the prompt just ask me to discuss not to differentiate which one has good benefit over other. So, I try this way :)
many thanks to give me different perspective in answering IELTS task 2.
