Can u clarify what person ur talking about and from what text
I think Dr Seuss has a way of making the books and easy read. Especially when it comes to kids he always is a fanatic in rhyming but it helped kids read easier. That's why I think hes popular for his writing.
There once was a kid named John. He was a young and adventurous kid. One day he went into the forest. He was sort of peculiar about it. His friends told him stories that there was a witch who made kids like him disappear. He wanted to prove them wrong that there wasn’t a witch. He soon came across an old, creaky house. He went inside, trying not to make a sound. He tried to see what was inside with his flash light. As soon as he turned around, he saw something dash across the hallway. He was curious. It looked like a dog to him. He went into the room that the thing went it. The witch was standing there, waiting for him. He grabbed John and tied him to the chair. She was stirring a potion. John was trying to yell for help, but he couldn’t. He was too deep into the forest. The witch forced him to drink the potion. Then … POOF! He disappeared, and John was never to be seen again.
The sentence that has an error in subject-verb agreement is D. The man, in the next apartment, as well as the people across the hall, have lived in the building since 1960.
Subject-verb agreement means that the subject of a sentence and the verb must agree in number. That is to say, both of them need to be singular or plural. In sentence D, the subject of the sentence is "the man" and the verb is "have lived". As the sentence refers to one man, the verb should be "has lived" in order to agree in number with the subject.
