The correct answer is B) Probably lacks a clear purpose.
When revising an essay, it’s a good idea to write down a sentence stating what your essay is about. If you can summarize it in one sentence, your essay probably lacks a clear purpose.
Remember that one of the most important things when writing an essay is to have a definite purpose. You have to choose a topic that can be of interest to your readers. Next, have a good outline considering the most important ideas to cover. Think of a good and powerful thesis statement to capture the attention of your readers. Be aware of the importance of a good introduction, develop the body of the essay and do not forget a good conclusion.
