问题     Male pilots flying general aviation (专用航空) (private) aircraft in the United States are more likely to crash due to inattention (疏忽) or flawed decision-making, while female pilots are more likely to crash from mishandling the aircraft. These are the results of a study by researchers at the Johns Hopkins University Bloomberg School of Public Health.
    The study identifies the differences between male and female pilots in terms of circumstances of the crash and the type of pilots error involved. "Crashes of general aviation aircraft account for 85% of all aviation deaths in the United States. The crash rate for male pilots, as for motor vehicle drivers, exceeds that of crashes of female pilots," explains Susan p. Baker, MPH (Master of Public Health, 公共卫生硕士), professor of health policy and management at the Bloomberg School of Public Health. "Because pilot youth and inexperience are established contributors to aviation crashes, we focused on only mature pilots, to determine the gender differences in the reasons for the crash. "
    The researchers extracted data for this study from a large research project on pilot aging and flight safety. The data were gathered from general aviation crashes of airplanes and helicopters between 1983 and 1997, involving 144 female pilots and 267 male pilots aged 40-63. Female pilots were matched with male pilots in a 1: 2 ratio, by age, classes of medical and pilot certificates, state or area of crash, and year of crash. Then the circumstances of the crashes and the pilot error involved were categorized and coded without knowledge of pilot gender.
    The researchers found that loss of control on landing or takeoff was the most common circumstance for both sexes, leading to 59 percent of female pilots’ crashes and 36 percent of males’. Experiencing mechanical failure, running out of fuel, and landing the plane with the landing gear up were among the factors more likely with males, while stalling (熄火，失速) was more likely with females.
    The majority of the crashes — 95% for females and 88% for males — involved at least one type of pilot error. Mishandling aircraft kinetics (动力学) was the most common error for both sexes, but was more common among females (accounting for 81% of the crashes) than males (accounting for 48%). Male, however, appeared more likely to be guilty of poor decisionmaking, risk-taking, and inattentiveness, examples of which include misjudging weather and visibility or flying an aircraft with a known defect. Females, though more likely to mishandle or lose control of the aircraft, were generally more careful than their male counterparts.
What is the research at Johns Hopkins University about?
选项 A、Causes of aircraft crash.
B、Gender difference in relation to types of aircraft crashes.
C、Causes of mishandling aircraft.
D、Gender discrimination in general aviation in the United States.
答案B
解析 定位在第1段，文章指出在美国，专用航空的男性飞行员更容易因为精神不集中或错误决定而坠机，而女性飞行员坠机的原因更多的是由于操作不当，上述就是约翰·霍普金斯大学布鲁姆博格公共健康学院的研究人员所做出的一项研究成果。选项B的意思为“不同性别的飞行员造成不同类型的飞行事故”，故正确答案为B。而选项D虽然也提及性别(gender)，却是性别歧视(genderdiscrimination)，故不能选。
