The summary overview is lacking in information. There must be a reference to the measurement type, which is by default, in the percentages. An enumerated listing of the 4 countries should have also been included prior to the mention of a few of these countries in the trending statement. The presentation is not comprehensive enough to be given a good preliminary score because of the lack of proper highlight considerations.
A trending statement needs to be clear and focused on presenting the high and low information. Your statement is a bit confusing for the reader. I know you were trying to write in an advanced manner, but the lack of proper sentence formation prevented you from presenting a heightened trending reference.
As can be seen from the chart,
The reader does not have a copy of the chart. You will lose points for asking the reader to "see" or "refer" to the chart for a better understanding of the information you are presenting. You should do that without requiring the reader to look at the image provided to you.
Failing to review and correct the errors in this essay, specially in the punctuation mark and run-on presentations, means that you are opening up the essay to lower score potentials all around. You should make sure to review and enhance the presentation, correcting errors whenever you can, within 20 minutes. You could have done better since you wrote only over 160 words in the essay. That indicates you still had time left to improve your presentation for a better final score.
