    Researchers【C1】______ 6.5 million car crashes and found a higher than expected number of accidents between two female drivers. They also discovered that women have a【C2】______time negotiating crossroads, T-junctions and slip roads. The results are even more【C3】______given that men spend more time【C4】______than women. On average, men drive 60 percent of the time, and women 40 percent.

    Dr. Sivak and his colleague Brandon Schoettle studied data from a nationally【C7】______sample of police-reported crashes in the US from 1988 to 2007. They【C8】______ to find that accidents involving two male drivers would make up 36.2 percent of all crashes, while female-female accidents would【C9】______15.8 percent and male-female 48 percent. 【C10】______, they discovered that accidents involving two women drivers were 20.5 percent, while male-male crashes were【C11】______ at 31.9 percent. Accidents involving male and female drivers【C12】______at 47.6 percent, as expected.
    The scientists also found that women were more likely than men to crash at a(n)【C13】______, and their cars were often【C14】______on the left-hand side when trying to make a【C15】______ turn, and vice versa. Dr. Sivak said this【C16】 ______be due to height difference【C17】______ the sexes.
    He said:" There are three【C18】______driver-related factors, including the【C19】______ of being at the wrong place at the wrong time, one’s own driving skills and the driving skills of【C20】______driver involved. "
