Some people are friendly drunks, whereas others are hostile, potentially posing a danger to themselves and others. The difference may【C1】______in their ability to foresee the consequences of their actions, according to a recent study. Brad Bushman, a psychologist at Ohio State University, and his colleagues asked nearly 500 volunteers to play a simple game. The subjects, an even mix of women and men, believed they were【C2】______against an opponent to press a button as quickly as possible. In【C3】______, they were simply using a computer program that randomly decided【C4】______they had won or lost. When they lost, they【C5】______a shock. When the "opponent" lost, the participant gave the shock and chose how long and【C6】______ it should be. 【C7】______playing, the participants completed a survey designed to【C8】______their general concern for the【C9】______consequences of their actions. Half the participants then received enough alcohol mixed with orange juice to make them legally【C10】______, and the other half received a drink with a very【C11】______amount of alcohol in it. Subjects who expressed little interest in consequences were more likely to【C12】______longer, stronger shocks. In the【C13】______group, they were slightly more aggressive than people who【C14】______about consequences. When drunk, 【C15】______, their aggressiveness was off the charts. "They are【C16】______the most aggressive people in the study," Bushman says. The good news is that this【C17】______can be changed. Michael McKloskey, a psychologist at Temple University, explains that if【C18】______people can learn to see the【C19】______more realistically, they"re able to stay calmer and develop a sense of【C20】______over their consequences.
【答案解析】解析：本句中出现的longer，stronger shocks对应第1段末句的how long and______it should be。第1段末句提到，如果“对手”输了，参与者给予电击(gave the shock)，并选择要进行的时长等。由此选择与gave同义的B项administer“给予”。

C
【答案解析】解析：本句中的they指代前文提到的对行为后果几乎不关心的研究对象(subjects who…)。本句提到这组人只比关心后果的人稍微好斗一点(slightly more aggressive)，后一句说到他们醉酒的状态。由此可知本句这里指的是没醉的时候，故填人C项sober“清醒的”。

【正确答案】
C
【答案解析】解析：上文提到这些人比关心后果的人稍微好斗一点(slightly more aggressive)，本句说到他们醉酒时。好斗性比平常强烈得多，off the charts意为much mole than usual“比平常要多”。因此这两句是转折对比关系，故答案为C项however。
