Explanation:
The form of mistakes that can be found in a sentence varies from punctuation or grammatical errors. And in that aspect, the determination of such errors can enable a person to make the required corrections.
In the given sentence, while there is an error n the subject-verb agreement, there is also an error in punctuation. This means that the subject-verb agreement is invalid or incorrect and also the correct use of commas wherever necessary.
