Answer and Explanation:
When choosing a subject to research and write about, we must be careful not to come up and stick to a topic that is too broad. If a topic is too broad, it allows for many subtopics to be derived from it, which means the research and the essay/speech will be all over the place. A narrower topic, on the other hand, will speak on a specific subject completely, without jumping from it to another. With that in mind, we can safely classify the following subjects in either "too broad" or "sufficiently narrowed" for a 500 to 800 word essay.
1. The Hawaiian Islands - Too broad. What about them? Their size? Their culture? Their people? Tourism?
2. The process of voting by caucus in primary elections - Sufficiently narrowed.
3. Lifestyle of women in rural Greece - Sufficiently narrowed.
4. Vacations in South America - Too broad. South America has several countries. Will we speak of each of them? Plus, what about the vacations? Their price? The best time to go? How long one should stay?
5. The health benefits of cottage cheese - Sufficiently narrowed.
6. Breakfast foods - Too broad. What about them? Which ones are more delicious? Which ones are the healthiest?
