The rapid fire of questions was deliberate, she knew, designed to scare her into （） out the truth.
A、knocking
B、blurting
C、blunting
D、dropping
【正确答案】：B
【题目解析】：本题考查动词短语辨析。knock out：（拳击中）击倒，打昏；blurt out：因为高兴或紧张而不假思索地脱口而出；blunt out：把……弄钝；black out：用墨等涂掉，熄灭灯光，眼前发黑。句子中动词后面的宾语是”the truth“，所以应该选择B选项”脱口而出“。句意：她知道，问题的迅速提出是故意的，目的是吓唬她脱口说出真相。
