Just be sure you can support it with evidence from your research. Avoid sexist language. Check your text for grammar and spelling, punctuation and contractions. Periods and commas go inside quotation marks. Semicolons and colons always go after quotation marks.
Periods go inside parentheses only if there is a full sentence inside the parentheses.
Check your paper for spelling. Computer spell-checks will not catch mistakes where your misspelling results in a different, but correctly spelled word. Always use complete sentences. This is the most common of the serious grammatical errors. When developing your argument, be clear, write simply, and double check grammar and spelling.
