<u>Which sentence has the correct subject-verb agreement?</u>
<em>B. Rising rivers mean trouble. </em>
<u>Subject-verb agreement</u> means the subject and the verb have to match in terms of number.
The subject <em>"rising rivers"</em> is plural, thereby, the verb must be <em>"mean"</em>. If the subject would have been singular, "rising river", the verb would have been <em>"means"</em>.
Another example would be:
- The<u> flying doves</u><em> </em>are beautiful (<u>plural</u> subject/ plural verb).
- The <u>flying </u><em><u>dove</u></em><em> </em> is beautiful (<u>singular</u> subject/singular verb).
