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