In ...support my opinion.
This is a totally unnecessary part of your presentation. You will not gain extra scores by repeating the writing instructions or explaining how you will be responding to the prompt. You will get scores based upon 3 sentence requirements only:
1. A complete restatement of the first public opinion
2. A complete restatement of the second public opinion
3. A complete statement of your personal opinion + your thesis statement
Your failure to clearly achieve these task requirements in the first paragraph means you will not be achieving a passing preliminary TA score. The essay itself is going to be scored as an incompletely developed presentation because there are no public opinion presentations, only personal opinion insights. There is no clear comparison between the public and your personal opinion. The essay will receive a failing score.
