Based on the hallmarks of essay grading, it's safe to say that the purpose of an essay is to state the author's opinion about paper help reviews. The structure of essay writing indicates that this opinion is bound to be confirmed.
Thus, defining the goals and objectives of the essay, we can say that the meaning of its writing is the substantiation of one's own vision of the essence, ways of solving some particular problem.
The text of the introduction does not specify goals or objectives, but if you do not know how to understand the essay, write it, then define them for yourself. The objectives are some kind of stages of work to reveal your vision of the situation.
To fully disclose the topic, analyze its relevance, so that the author can make his own understanding of what is happening, examining the manifestation of the problem on the theoretical and practical levels, looking for new, unconventional ways of solving.
If we arrange these tasks in a logical order, considering that these are some elements of an essay, then:
The introduction analyzes the relevance of the issue under study, outlines the main problem, the importance of solving it.
The main part contains an analysis of the essence of the problem, its manifestation at the practical and theoretical levels, supported by arguments.
The conclusion describes the vision of the situation through the eyes of the author, his proposed ways of solving the problem.
