Questions: Read the sentences from Barrio Boy by Ernesto Galarza. I grabbed the chain with both hands and pulled. A small torrent of water gushed into the bowl, swirling and disappearing down the drain with a deep, sonorous gargle. I waited a few minutes and pulled the chain again. That night I got up several times to go to the toilet, until I was ordered to go to sleep. Why does Ernesto go to the toilet several times? He has an upset stomach. He is fascinated by the invention. He drank a lot of water with his dinner. He is trying to get his mother's attention.

The answer is B: He is fascinated by the invention.

Explanation for each option:

• He has an upset stomach. This option is incorrect because the text does not mention any symptoms or indications that Ernesto is feeling unwell or has an upset stomach. The focus is on his actions and curiosity rather than any physical discomfort.

• He is fascinated by the invention. This option is correct. The text describes Ernesto's repeated actions of pulling the chain and watching the water swirl and disappear, which suggests that he is intrigued by the mechanism of the toilet. His fascination with the invention is further implied by his repeated visits to the toilet, even being ordered to go to sleep.

• He drank a lot of water with his dinner. This option is incorrect because the text does not mention anything about Ernesto drinking a lot of water. The emphasis is on his interaction with the toilet, not on any consumption of liquids.

• He is trying to get his mother's attention. This option is incorrect because there is no indication in the text that Ernesto's actions are aimed at getting his mother's attention. The narrative focuses on his curiosity about the toilet rather than any attempt to communicate with his mother.
