Answer:
The incorrect verb is highlighted below:
Beneath Puerto-Princesa Subterranean River National Park in the Philippines flow an underground river that empties into the Pacific Ocean.
The correct verb would be:
Beneath Puerto -Princesa Subterranean River National Park in the Philippines flows an underground river that empties into the Pacific Ocean.
Explanation:
The sentence above states facts using the Simple Present Tense. When using that tense, third-person singular verbs must be conjugated to agree with the subject. We can add -s, -es, or -ies, depending on the verb's ending. For example:
- I look - he looks
- You watch - she watches
- They cry - it cries
In the sentence, the subject of the verb "flow" is "river", which is a third-person singular subject (equivalent to "it"). For that reason, "flow" needs to be conjugated, becoming "flows". Notice that the verb "empties" that appears next is properly conjugated in its third-person form to agree with "river", and so should "flow". Therefore, the correct sentence is:
Beneath Puerto -Princesa Subterranean River National Park in the Philippines flows an underground river that empties into the Pacific Ocean.
