"It is important to both choose and adjust the tone (style) of our essay. The formal essays, which are designed for professional and academic contexts, use more complex sentences, express a more limited range of emotions, sound less personal, and use no contraction or fewer simplified words. By contrast, the informal essays, written for personal reasons, tend to use simpler sentences as well as word choices, express a wider range of emotions, sound more personal and friendlier, and include contraction."

Now as for this topic, sort styles which this essay should be written in from the most suitable (()) to the least suitable (()).
