sparks off an intense debate in modern society
This statement will cost you point deductions in the TA section. There is no reference to such a thing in the original presentation. In fact, this statement has changed the discussion considerations from the original prompt, creating a separation between your interpretation and the first version of the topic. This will make your version get a failing score.
I find myself leaning towards the former outlook.
You are not responding to the task in the correct format. Your opinion will receive a failing score. You are asked to respond in a measured extent manner, something that you failed to do in your opinion presentation.
The actual discussion is also incorrect since you did not provide the correct single opinion defense in the presentation. You used a comaparison discussion, meaning you failed to address the prompt writing instructions. So the essay will not receive a passing score. You did not follow the correct writing instructions.
