Read the article and select the best answer. Article: How good are U.S. drivers? The CBS TV "National Drivers Test" showed that many U.S. drivers have a lot to learn. Here's why: CBS picked 1,799 samples to take the test in TV studios in New York, Philadelphia, Chicago, and Los Angeles. More than two out of five of the drivers failed the test. And the average score was the lowest passing mark-51 points out of a possible 80. Chicago drivers did best with an average of 53 points. Los Angeles drivers came next with 52 points. New York and Philadephia drivers tied with 50 points-a failing score. Drivers with 50 points or less were rated "poorly informed" by the judges. Here are some of the test results: (1) Are men better informed drivers than women?-Yes. Men averaged 52 points. Women got average of 49. (2) Are older drivers better informed than younger drivers?-No. Drivers under 26 averaged 52 points. Drivers from 27 to 45 averaged 51. Driver over 45 failed with 48 points on average. (3) Does education make a difference?-Yes. College graduates averaged 52 points. High school graduates averaged 50. Those without high school diplomas got 48. And people who had taken driver education courses scored an average of 53 points-three more than those who hadn't. (4) Does driving experience make a difference?-Yes. Drivers with three or more years' experience averaged 51 points. Drivers with less experience averaged 49. Here are some surprising facts brought out by the test: (1)More than one out of three drivers did not know that a blinking red light means a full stop. (2)Three out of ten drivers did not know that an octagonal (eight-sided) sign means stop. (3)More than two of three drivers did not know what to do when being "tailgated"(,) The answer: slow down, drive to the right, and let the driver behind pass. The results of the test were turned over to the National Safety Council. They will help future safety planning. Question: The author's purpose is to _ . Options: A: prove that men are better drivers than women B: give you safe driving tips C: tell you the results of a national drivers test. D: urge you to get an education.

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: The research on the American cattle egret Options: A: must be meaningless to other animals. B: will mainly take place in the laboratory. C: should be very easy due to the existing fact. D: can help discover how animals adapt to the environment.
