You write a comparison essay when you have no option but to convince a reader to agree to your point of view with comparisons. This normally happens when readers have certain preconceived ideas about certain events or objects that are deep rooted. It then becomes very difficult to remove the notion with the help of examples unless you compare the idea with a more powerful and compelling idea that readers would find difficult to contradict.
When you write a comparative essay, you are making comparisons for the benefit of the reader. It becomes very important for you to do so with the intention of convincing a reader of the merits of your argument. This becomes possible when you draw a powerful comparison between two opposing viewpoints. You have to be careful here that viewpoints are common and well known to readers. Only then will they be able to relate to both points of view.
Essay questions are asked when you have doubts about the topic or about sources of research material that is needed. You could be apprehensive about the probability of a condition being true, and you may not be very sure about the point you are making. You have to clear doubts before going ahead. The same set of conditions probably exists in the minds of readers who need clarification at the exact point when a doubt arrives in their minds. If you are not able to provide the justification to the argument placed at that point or if you are not able to clear their doubts, you have a difficult task in retaining interest among readers.
As you refer to essay samples on similar topics, you get an idea of what is needed to retain interest among readers. The ideal way to do this is to read those samples and see for yourself if all your doubts are cleared. Think like a reader, and your work would become much easier when you have to write your own essay.
Most essay writers rely on their own style of writing and practice how to generate a rhythm for writing comparison essays that matter. Relate to live events that you came across and remember incidents that you could relate to, those which convinced you that a certain point of view was right. Use these examples in essays. People relate to real-life incidents much more positively that you would think it to be possible.
Assessors generally tend to treat any essay with a measuring scale they have of their very own to assess the merits of an essay. This is generally done by comparing an essay to another one on the same topic. This is very similar to an evaluation essay. Each point is often compared to relevancy and in comparison to optimum explanations for the same or similar point in terms of presentation, research quality, usage of grammar and sentence structure. Writing well comes with practice and the more you practice the better you become. As you relate to the way readers think and are able to convince them with the right blend of arguments and comparisons, you will get better at choosing topics with relevant ease for your comparison essay.
