This question is about "Barrio boy"
Answer and Explanation:
Galarza is apprehensive about going to American school, but he was anxious about how he could learn English and become a proud American, as he himself says.
When he arrives at school he gets tense, because he thought that the teachers could be rude and that he would be the only boy not to speak English, but he had a very different experience, which helped him a lot to form a thought about the country in which he was living. First, the teachers were very kind and patient and taught him English very calmly. He was not the only foreigner and had the company of many friends, even Americans who helped him to speak correctly. Galarza then realized that this was a country that also had kind and solicitous people.

Section headings</span>
Section headings serve as guide to the reader,
marking the different subdivisions and topics to be discussed. By simply
looking at a text with section headings, the reader can see the overview of the
whole article or essay. However, long paragraphs bore the reader and ruin the
interest of the reader. Likewise, abstract technical vocabulary distracts the
reader’s attention and makes the passage appear difficult to understand. Lastly,
complex sentence structure is similar to long paragraphs. They make the reader
lose interest in the material and often miss the main idea being explained.
