In order to get a better TA score, you need to meet some sentence representation requirements:  
- Proper restatement of the original prompt  
- Direct responses to every question posed  
  
This is called outlining your discussion points for the examiner. This will help to show that you understood the original topic, the discussion instructions, and the response format requirements. In this case, your restatement was alright, but the outline of the discussion is vague. A vague response normally results in a presentation that does not offer a clear discussion per paragraph.  
  
Now, the essay is not asking you to provide several reasons and solutions with regards to the sugary drinks problem. You should have used the 4 paragraph format for this discussion offering:  
  
Par. 1: The prompt restatement and discussion topic presentations (reason-solution in the singular)  
Par. 2: A thorough discussion of a single reason  
Par. 3: A clear discussion of a solution in relation to the previously stated reason (for coherence and cohesive scoring purposes)  
Par. 4: A summary of the preceding discussion (topic, reason, solution, closing statement)  
  
You have a formatting problem in your 1st reasoning paragraph that left the presentation under developed. You used too many word fillers and not enough relevant explanations and expanded example discussion in the presentation. A more appropriate format would have been:  
  
-Topic sentence  
- Explanation  
- Example  
- Reason or explanation that relates the previous explanation of the topic to the example  
  
There was no need to present a second reason as there was no plurality involved in the reasoning discussion. The paragraph would have been fully developed and explained if you had used the format above and also, omitted the discussion of the second reason as a part of that paragraph. Since you also offered under explained and unrelated solutions, you cannot expect to get a high TA score for your essay.  
  
TA score 6. You could score better once you learn to develop connected reasons and acquire the ability to use transition sentences/phrases/words that will help you move from one paragraph topic to the next paragraph topic. Again, unless plural reasons and solutions are specified, use only one of each to help you fully cover all the required discussion points.  
  
C&C would be 5. Like I said, you did not adequately develop your explanations, there was no use of transition statements from paragraph to paragraph, and the discussion topics you presented as per reason and solution requirements were not fully connected from one discussion to the next. Hence the lower score.  
  
LR score is a 6. You have an adequate grasp of basic English vocabulary to help you explain yourself in the paragraphs. The words used sounded normal and not as if you were merely trying to impress the examiner. Which is the main reason for the better LR score. You sounded like you were just having a proper basic English conversation. Try to use some natural sounding advanced words to help increase the score next time. Or, whenever you are ready. Keep building on your vocabulary by watching more English programs and reading more electronic and print media in English. Yes, even English subtitles in movies count.  
  
GRA, is another 6 score. Any grammar errors you have do not create a difficulty in understanding your explanations. However, that does not mean that you provided complete explanations. Do not confuse the GRA review with the TA review. You still lack properly developed paragraph discussions as per the TA scoring requirements. The GRA score just means that, without considering the TA requirements, you presented some well written sentences in terms of punctuation mark usage and simple to complex sentence development. Nothing more.  
  
Final score, based on my scoring considerations could at the 6 mark. You have shown the potential to reach and 8. You just need to practice more and develop your discussion clarity based on the different Task 2 discussion types.
