Which statement about quotation marks is true?

The statement that quotation marks always come in pairs is true. Quotation marks are punctuation marks used to denote direct speech, quotations, or specific titles. When using quotation marks, you start with an opening quotation mark and end with a closing quotation mark, forming a pair around the text you want to highlight or denote as spoken or cited. This pairing is essential for clarity in writing, as it helps readers understand the boundaries of the quoted material.

The other statements do not accurately reflect the rules governing quotation marks. While quotation marks may appear similar to other punctuation marks, such as commas or apostrophes, they serve distinct purposes in writing. It's also worth noting that quotation marks can indeed appear at the beginning of a sentence, especially if the sentence includes a quotation. Thus, the requirement for quotation marks to be in pairs is a fundamental rule in punctuation that allows for proper representation of quoted material.
