How to write an essay?

Exist many kins of essays, but I'll focus on one: Compare and contrast Essay.
A comparative essay asks that you compare at least two (possibly more) items. These items will differ depending on the assignment. You might be asked to compare

• Positions on an issue (e.g., responses to midwifery in Canada and the United States)
• Theories (e.g., capitalism and communism)
• Figures (e.g., GDP in the United States and Britain)
• Texts (e.g., Shakespeare’s Hamlet and Macbeth)
• Events (e.g., the Great Depression and the global financial crisis of 2008–9)

You can organize the essay in this way:
