What is the agreement error in the sentence: Although they seemed inflamed, the site of the previous carnietomy seemed free of defect.
they . . . the site
The pronoun should be singular, "it," to agree with the singular, "the site."
They:site
The agreement error in the sentence is the incorrect agreement between the subject "site" and the verb "seemed." The subject "site" is singular, while the verb "seemed" is plural. To correct this error, we need to ensure that the subject and verb agree in number.
To fix the agreement error, we can change the verb "seemed" to its singular form, which is "seemed." The corrected sentence would be: "Although it seemed inflamed, the site of the previous carnietomy seemed free of defect."
