问题     A recent study by researchers at the University of Maryland predicted a person’s score on a personality test to within 10 percentage points by using words posted on Facebook.
    Golbeck and her colleagues at the university’s Human-Computer Interaction Lab surveyed the public profiles of nearly 300 Facebook users this year. They looked at users’ descriptions of their favorite activities, TV shows, movies, music, books, quotes and membership in political organizations. They also looked at Facebook’s public "About Me" sections.
    The 300 participants then took a standard psychological exam that measures the "big five" personality traits: openness to experience, conscientiousness(责任心), extroversion(外向性), agreeableness and neuroticism(神经质).
    People who tested as extroverts on the personality test tended to have more Facebook friends, but their networks were more sparse(稀疏)than those of neurotics, meaning that their friends were less likely to know one another than were the friends of other Facebook users. People who tested as neurotic had more "dense" networks of people who know one another and share similar interests.
    The researchers also found that people with long last names tended to be have more neurotic traits, perhaps because "a lifetime of having one’s long last name misspelled may lead to a person expressing more anxiety and quickness to anger, " according to the study. People who tested high on the neurotic scale also tended to use a lot of anxiety-associated words, such as "worried, " "fearful" and "nervous, " on their Facebook posts. They also use words describing eatings "pizza, " "dish", "eat."
    Golbeck says she can’t explain that last correlation. "You’d have to get a psychologist on that one, " she said. "It could be that people that are neurotic talk more about what they are eating. It could be a deep correlation that we can’t understand on the surface."
    Golbeck says that evaluating a person’s personality is important to anticipating how well they will get along with others in school or a job. But some critics say that you can’t really use social media to figure out human behavior.
What do researchers find about people tested as extroverts?
选项 A、They have more Facebook friends who may not know each other.
B、They are leaders who organize all kinds of activities.
C、They get along much better with their friends.
D、They share more interests with their friends.
答案A
解析 根据题干关键词people tested as extroverts定位到第四段第一句：People who tested as extroverts on the personality test tended to have more Facebook friends，but their networks were more sparse than those of neurotics，meaning that their friends were less likely to know one another than were the friends of other Facebook users．个性测验中为外向型的人倾向于有更多的Facebook朋友。但是他们的网络比起那些神经质的人要稀疏一些，这意味着比起其他Facebook使用者，他们的朋友不太可能彼此认识。A)项是原文的同义转述，故为答案。
