Tell what person, what type, and how you know.

Mr. Morton knew the students were running out of time, but he felt that he needed to give an example of the activity, so he did. One of his students raised his hand. "Yes?" Mr. Morton asked. "I know I'm going to have problems with this," said the student.
The student went on, "I mean, what about when characters reveal their thoughts through dialogue? Does that count?"

I think it would be Third Person Limited because the internal narration is limited to Mr. Morton

I agree.

In this passage, Mr. Morton is the person mentioned. He is the one who knew that the students were running out of time and decided to give an example of the activity. The passage also mentions a student who raises his hand and asks a question.

As for the type of narration, it appears to be Third Person Limited. This is because the passage focuses on Mr. Morton's perspective and his internal thoughts. We only get insight into Mr. Morton's thoughts and not those of other characters. The student's question also adds to the evidence that it is from Mr. Morton's limited perspective since the question is about characters revealing their thoughts through dialogue.

To arrive at this conclusion, I analyzed the passage and identified the characters involved, their actions, and the information provided about their thoughts and perspectives. By considering these factors, I determined that the narration is from Mr. Morton's limited point of view.
