Q: Read the article and select the best answer. Article: The cattle egret has lived in American continent in recent years. Non-native species are a worldwide problem and studies are devoted to assess the damage they cause to local species populations. The cattle egret primarily lives on the grassland and feeds in close association with animals like cattle and sheep. This bird is native to Africa, southern Europe and western Asia. The cattle egret in Brazil is unlike a number of bird species that have been established and expanded to non-native areas through human assistance. The first sight of the cattle egret in the New World were reported between 1877 and 1882, followed by sightings in British Guiana and Colombia and later expansion throughout the Americas. In Brazil, the cattle egret was first recorded in the northern region of the country in 1964, feeding along with buffalos on Marajo Island in the state of Para. While the cattle egret is not currently a threat to native animals and birds in Brazil throughout most of its geographic distribution, it has the potential to produce bad effects, as evidenced by its occupation of island environments. For example, in the Fernando de Noronha archipelago, the cattle egret drives adult native seabirds away from their nests in producing time. Understanding how the cattle egret settled and lived in Brazil is important for the better understanding of spreading patterns of bird populations and their interaction with the local species. Explaining the egret cattle's settling in the Americas is a challenging task due to the lack of sufficient information and reports on entrance time, location, and number of events. Comparisons between native and non-native populations can provide a 'natural' experimental way to clarify the biological and environmental factors that may contribute to range expansion and adaptation to climate change, and to find how animals respond to strange and sudden ecological and environmental pressures.

Question: Read the article and select the best answer. Article: Country-dwellers often say the constant noise, heavy traffic and crowds of the city would drive them mad. Well, they might be right, according to the latest research. City residents are more likely to develop mental illnesses than those who live in villages, a study has found. Researchers from Cardiff university examined the lifestyles of more than 200,000 people in Sweden and found that those who lived in urban areas were more at risk from mental illnesses than people who lived in villages. The experts don't know exactly why this is but they suggest that town and city residents are more likely to be ostracized by those around them. They are more likely to experience discrimination if they do not fit in, which can lead to them feeling anxious and even developing mental illnesses. Dr Stanley Zammit, who led the research said that people living in towns and cities are more likely to develop other mental illnesses that result in personality changes -- a condition known as non-affective psychosis . Earlier this year an official report found that village-dwellers live an average of two years longer than those living in towns and cities. According to figures from the Office of National Statistics in the UK, men who live in villages are likely to live for between 78 and 79 years, while those in towns and cities can expect to survive to an age of 76. Women on average survive to their 81stbirthday in towns and cities, but live to between 82 and 83 in villages. The small marked town of Wimborne Minster in rural Dorset was named the healthiest place to live in. Question: The research from Cardiff University was based on the people's _ . Options: A: interests. B: characters. C: occupations. D: lifestyles.

Q: Read the article and select the best answer. Article: The horsepower was first used two hundred years ago. James Watt had made the world's first widely used steam engine. He had no way of telling people exactly how powerful it was, for at that time there were no units for measuring power. Watt decided to find out how much work one strong horse could do in one minute. He called that init one horsepower. With this unit he could measure the work his steam engine could do. He discovered that a horse could lift a 3,300-pound weight 10 feet into the air in one minute. His engine could lift a 3,300 pound weight 100 feet in one minute. Because his engine did ten times as much work as the horse, Watt called it a ten-horsepower engine. Question: Watt wanted to find a way _ . Options: A: to lift a 3,300-pound weight B: to show how useful his steam engine was C: to tell people exactly how powerful his steam engine was D: to measure the weight of his steam engine
A: C
