Identify the sentence that uses possessive apostrophe correctly.

Identify the sentence that uses possessive apostrophe correctly.

• A. The researchers' findings were replicated in a separate lab.
• B. The researchers' findings were replicated in a different lab.
• C. The researchers' findings were not replicated.
• D. The researchers' findings were found invalid in another lab.

Answer: (A)

Placing the apostrophe after the final s in a plural noun shows possession by that plural. In this sentence, researchers is plural, and the apostrophe after the s (researchers') indicates that the findings belong to the researchers. The rest of the sentence—that the findings were replicated and where—uses normal, clear wording, making the meaning straightforward. So the possessive is shown correctly by putting the apostrophe after the s in researchers.
