I have a task to prepare an essay on any topic which found ideal for us. This task is to check our reasoning limit and innovative thoughts. Our institute has chosen to lead an essay rivalry. I need to take part in that. Lots of students has interest to participate in that. The count of members is more than they chose. So to shortlist the members the administration has chosen to give a task to prepare an essay on any subject. I am confused about how to pick a best subject.
