But don't forget, even if you have all the right qualifications and interview skills, you should not arrive late for your job interview!

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

  Accidents do not occur at random. People eighty-five years of age and older are twenty-two times likelyto die accidentally than are children five to nine years old. The risk for native Americans is four times that for Asian-Americans and twice that for white Americans or African-Americans. Males suffer accidents at more than twice the rate of females, in part because they are more prone to risky behavior. Alaskans are more than three times as likely as Rhode Islanders to die in an accident. Texans are twenty-one times more likely than New Jerseyites to die in a natural disaster. Among the one hundred most populous counties, Kern County, California (Bakersfield), has an accident fatality rate three times greater than Summit County, Ohio (Akron).

  Accidents happens more often to poor people. Those living in poverty receive inferior medical care, are more apt to reside in houses with faulty heating and electrical systems, drive older cars with fewer safety features, and are less likely to use safety belts. People in rural areas have more accidents than city or suburban dwellers because farming is much riskier than working in a factory or office and because emergency medical services are less readily available. These two factors - low income and rural residence - may explain why the south has a higher accident rate than the north.

Tai nạn không xảy ra ngẫu nhiên. Người từ 85 tuổi trở lên có khả năng chết do tai nạn cao hơn 21 lần so với trẻ em 5-9 tuổi. Nguy cơ cho người Mĩ bản địa gấp 4 lần người Mĩ gốc Á và 2 lần người Mĩ da trắng hoặc người Mĩ gốc Phi. Nam giới chịu tỉ lệ tai nạn cao hơn 2 lần nữ giới, một phần vì họ có xu hướng thực hiện các hành vi mang tính rủi ro nhiều hơn. Người Alaska có khả năng chết do tai nạn gấp 3 lần người ở Rhode Island. Người Texas có tỉ lệ chết trong thảm họa tự nhiên nhiều hơn người New Jersey 21 lần. Trong 100 hạt đông dân nhất, hạt Kern, California (Bakerfield) có tỉ lệ tử vong gấp 3 lần hạt Summit, Ohio (Akron).

Tai nạn xảy ra thường xuyên hơn đối với người nghèo. Những người sống nghèo khổ nhận được dịch vụ y tế kém, thường ở trong những ngôi nhà có lỗi về hệ thống sưởi hoặc điện, lái những chiếc xe cũ hơn với ít tính năng an toàn hơn, và ít dùng dây an toàn hơn. Người sống ở nông thôn gặp tai nạn nhiều hơn người thành phố hoặc người ở vùng ngoại ô vì việc đồng áng nhiều nguy cơ hơn hẳn làm việc trong một nhà máy hay văn phòng và bởi dịch vụ cấp cứu ít sẵn có hơn. Hai nhân tố này - thu nhập thấp và sinh sống ở vùng nông thôn - có thể giải thích được vì sao miền nam có tỉ lệ tai nạn cao hơn miền bắc.
