Please choose the correct ending to complete the given sentence: Education and Communications: [header] How to avoid common essay mistakes [title] Choose a topic with appropriate scope. [step] Sometimes a topic will be assigned to you, but if that is not the case, you must select your own topic for the essay. You might be inclined to choose a topic that is overly broad or too narrow, which is a common pitfall.

Ending1: [substeps] Narrow your topic to include broad ideas or themes. Otherwise, you might choose a topic specific to some aspect of your life and avoid being charged with essay misconduct. Ending2: Instead, try to choose a topic that is both focused and will also allow you to compose an essay in its entirety. [substeps] For example, you do not want to compare all of africa to all of asia because that topic would be too broad or too general. Ending3: [substeps] If you want to tackle a major issue on a topic like biology, for example, don't choose an obscure topic like chemistry. If you want to focus on a specific issue, maybe choose a topic that has been covered for a long time, like biology. Ending4: By choosing a topic that is broad, you will avoid these mistakes. [substeps] For example, for a history topic you might pick a subject that has a broad scope, such as american history.
