What is "(sic)"
19. Inclusive language-quoting from biased material - The mayors and their wives were invited on a tour of the state buildings.
answer: The mayors[sic] and their wives were invited on a tour of the state buildings
"Sic" is Latin for "thus" and means "intentionally so written" here, signifying that the preceding text is meant to be read as is, and not corrected should you find something wrong with it.

Your answer is basically correct, with two more corrections!
answer: The mayors [sic] and their wives were invited on a tour of the state buildings.
Put a space after "mayors."
Italicize the letters "sic."
Put a period at the end of the sentence.
Sorry -- three corrections!
"(sic)" is a Latin term that is used in writing to indicate that an error or unconventional usage in a quote has been reproduced exactly as it appeared in the original source. It is typically placed in square brackets after the error or unconventional usage.
In the given example, the word "mayors" is followed by "(sic)" in square brackets - "mayors[sic]". This indicates that the word "mayors" is being quoted exactly as it appeared in the original source, even though it may be incorrect or unusual. It is used to clarify that the error or unconventional usage is not a mistake on the part of the person quoting the source.
So, in the corrected sentence, the original source mistakenly used the word "mayors" instead of the correct term "mayors'". By including "(sic)" in square brackets, the sentence now accurately conveys the words used in the original source, while also indicating that "mayors" is an error and should actually be "mayors'".
