I really appreciate all of the suggestions. An outline is just a mere representation of how an essay is being written. I agree that few of the topics are redundant. However, their inclusion isn’t unnecessary if one knows how many words are enough to cover them. Topic 2 needs to be covered in a concise way which shouldn’t be too long nor too small. Instead of opinion, exact information is required in this section. Apart from that, I did not merge topic 3 and 4 because topic 3 needs to be covered by keeping the views of different subjects like sociology, law, economics, political science etc. with reference to the essay. Topic 4 is based on opinion and justification for the later part of an essay which is “nationalism”. I intentionally kept the topic 6 limited to cover the essay on time. However, its lengths and arguments can be varied based on the available time. Thanks and once again, I appreciate all those who replied as your suggestions are how others learn from your experience.
