Read the following article and answer the question. Article: My father was a foreman of a sugar-cane plantation in Rio Piedras, Puerto Rico. My first job was to drive the oxen that ploughed the cane fields. I would walk behind an ox, guiding him with a broomstick. For $ 1 a day, I worked eight hours straight, with no food breaks. It was very _ work, but it prepared me for life and taught me many lasting lessons. Because the plantation owners were always watching us, I had to be on time every day and work as hard as I could. I've never been late for any job since. I also learned about being respectful and faithful to the people you work for. More important, I earned my pay; it never entered my mind to say I was sick just because I didn't want to work. I was only six years old, but I was doing a man's job. Our family needed every dollar we could make because my father never earned more than $ 18 a week. Our home was a three-room wood shack with a dirty floor and no toilet. Nothing made me prouder than bringing home money to help my mother, father, two brothers and three sisters. This gave me self-esteem , one of the most important things a person can have. When I was seven, I got work at a golf course near our house. My job was to stand down the fairway and spot the balls as they landed, so the golfers could find them. Losing a ball meant you were fired, so I never missed one. Some nights I would lie in bed and dreamt of making thousands of dollars by playing golf and being able to buy a bicycle. The more I dreamed, the more I thought. Why not? I made my first golf club out of guava limb and a piece of pipe. Then I hammered an empty tin can into the shape of a ball. And finally I dug two small holes in the ground and hit the ball back and forth. I practiced with the same devotion and intensity . I learned working in the field -- except now I was driving golf balls with club, not oxen with a broomstick . Question: Which of the following statements is true according to the passage? Answer:
OPTIONS:
- He wanted to be a successful golfer.
- He wanted to run a golf course near his house.
- He was satisfied with the job he got on a plantation.
- He wanted to make money by guiding oxen with a broomstick.

Answer: He wanted to be a successful golfer.

Read the following article and answer the question. Article: Although cats may be one of the most popular pets today, little is known about how and when humans and cats set up their close relationship. The earliest evidence for human-cat interaction dates back to prehistoric Cyprus , where the remains of a wild cat and a human -- dated 9,500 years old -- were found buried together. A new study in the Proceedings of the National Academy of Sciences has confirmed the first direct evidence of a human-domestic cat relationship among Chinese farmers 5,300 years ago. Researchers studied the bones of cats, dogs, deer and other animals unearthed in an excavation near a village in Central China. By using some ways, scientists showed that the cats were living on a mostly millet -based diet, just like the domesticated dogs and pigs from the site. "The most reasonable explanation for a high consumption of millet-based food is that the cats had formed a stable and mutual relationship with humans and could easily feed on rodents around human villages, find leftover food or even have been fed by people intentionally," said Hu Yaowu from the Chinese Academy of Sciences in Beijing, whose research focuses on the relationship between humans and domesticated animals. "It is very interesting for us to find the consumption of millet-based foods by the cats, since this kind of evidence had long been missing." Hu explains. Since cats usually eat meat, such a diet would be unexpected, unless the cats were being fed by people, the study argues. The researchers also found that one of the cats survived to reach old age, implying that it had a safe place to live and enough to eat. Why the farmers wanted to keep cats nearby or make them "pets" could be answered by other evidence. Chinese archaeologists found some storage containers were specifically designed to keep out rodents -- a vermin that cats could certainly have helped with. The simplified theory is that rats were attracted to the food of farmers, and so were harmful to farmers. Cats were attracted to the rats, and so farmers formed a... Question: Apart from cats, Hu Yaowu and his teams may also study _ . Answer:
OPTIONS:
- the preventions of pests from grains
- the history of Chinese farming
- the dogs and pigs
- the ways to keep pets

Answer:
the dogs and pigs
