I did the same thing too but I didn't add anything about the disadvantages since the question only told you to demonstrate how technologies..etcI explained how cataract surgery, myopia, damages to the inner, middle and outer ear can be corrected using cataract surgery, LASIK, Hearing aids and cochlear implant. In my response I explained the surgery/technology in detail about how it worked. Only wrote like one -two sentences on each about how this helps overcome communication problems. I didn't include any diagrams. I also wrote a little dot point thing about how there are some disadvantages associated with the technology/surgery.
Is this was they were asking for?
Did most people do this?
