单选题 The passage states that before the blue square appeared, the person in the video ______.

【正确答案】 D
【答案解析】细节题。
[解析] 根据题干中的关键词before the blue square appeared定位到原文第二段,我们了解到电脑屏幕上兰色方格出现,受实者会被电击。因此下一次兰色方格出现时,他非常紧张害怕。直到最后一句And he's already in distress before he receives the shock,you see him anticipate receiving the shock,D)中got ready to是对原文anticipate的近义转述。
