Your explanation is generally fine. Your writing has met all of the criteria required by this task. The diagram is clearly explained. There might be a few mistakes about grammar e.g. the use of full stops, starting the sentence with no subject; "Exploitation of children." "Make exploitation Deceived and forced easy." "Which affect the progress of the nation." "And is a problem that undermines the stability of the human." Otherwise, it is a good piece of work. Keep practicing and your writing skill will improve tremendously.
