Just like the hamburger, paragraphs and essays have five parts.
The lettuce isn't the most important ingredient, but it still needs to be fresh and crisp.
There is one important side issue: All three reasons must be grammatically "parallel". That means each reason has to match the other two grammatically, essentially be the same part of speech. All three reasons must be nouns, adjectives, adverbs or verbs. If they are verbs, they must be the same verb tense and form.
If you understand parallelism, move on to the tomato.
