The essay is below the required minimum word count. The word percentage deductions tells me that you either did not know about the minimum word requirement or, you were hesitant in your writing due to a lack of knowledge on the topic or, a low English vocabulary level. Either reason is not good for your TA score as the low word count will mean TA score deductions based on the minimum word requirement. The essay has already failed the preliminary assesment even before the actual written content has been considered based on the 4 scoring sections.
There is a topic presentation in the first paragraph but no thesis statements based on the 2 discussion targets. Providing the 2 thesis sentences provides a summary of your upcoming discussion and will show how well you understood the questions in relation to the overall discussion. These thesis sentences help to increase your TA score based on your related discussion points in relation to the provided topic and questions, which are the basis for your 2 expanded reasoning paragraphs.
It is impossible for them to improve their conditions.
Hyperbolic assessments and exaggerations should not be included in the discussion as it could create topic deviations in your presentation. For instance, there are success stories based on the way that little educated people manage to become rich, or at least, lead financially stable lives. Avoid over exaggerations as that is not the same as emphasizing a point.
The reasoning paragraphs have an uneven explanation development. The causes paragraph is far better explained than the solutions portion. The second paragraph needs more explanations to support the solutions. I believe that it is the lack of discussion development in this paragraph that led to the lack of word count.
You do not have a problem understanding the prompt. You have a problem discussing the topic for unknown reasons. By the way, never use contractions in an academic essay. Always use the full 2 words due to formal writing requirements.
Next time, try to write more words. That is the only way you can meet minimum scoring requirements.
