What is the difference between a topic and a main idea? The topic is the general subject of a paragraph or essay. Topics are simple and are described with just a word or a phrase. The main idea is a complete sentence; it includes the topic and what the author wants to say about it.
The first one has alliteration in the beginning, but not in the end. The 2nd sentence is barely alliteration, the 3rd one has no alliteration, and teh 4th sentence repeates the -eed sound.
