It
is false that all paragraphs should
have one main idea. A paragraph does not necessarily need a topic
sentence when you write an essay. Because in an essay, there is already a topic
given, all you have to do with the successive paragraphs you are writing is to
write things related to the topic given. Every paragraph in the essay must be a
subtopic to the overall topic therefore having another topic in each paragraph
will make your essay incoherent and unparalleled in ideas perspective
