I keep coming across these (I know they have not all been assigned yet, but they are BASIC), so here are some quick answers; look up the reasons in the Rules for Writers (RW)!
–The man WHO, not the man THAT.
–Quotation mark placement, e.g., “dogs,” not “dogs”,
–, and in a series, e.g., “dogs, cats, and mice.”
–Spell out most numbers; spell out “percent.”
–Use parallel structure!
–No comma splices!
–The mysterious “They.” Highlight every use of this in your paper. Is it clear who “they” are? If not, edit!
–Dangerous passive voice, e.g., “Human trafficking IS CONSIDERED the fastest growing crime.” Use active voice, e.g., “Many authoritative researchers deem human trafficking to be the fastest growing crime.”
