Some young soldiers who had recently joined the army were being trained in modern ways of fighting,and one of the things they were shown was how an unarmed man could trick an armed enemy and take his weapon away from him．First one of their two instructors took a knife away from the other,using only his bare hands;and then he took a rifle away from him in the same way．After the lesson,and before they went on to train the young soldiers to do these things themselves,the two instructors asked them a number of questions to see how well they had understood what they had been shown．One of the questions was this:“Well,you now know what an unarmed man can do against a man with a rifle．Imagine that you are guarding a bridge at night,and that you have a rifle．Suddenly you see an unarmed enemy soldier coming towards you．What will you do?” The young soldier who had to answer this question thought carefully for a few seconds before he answered,and then said,“Well,after what I have just seen,I think that the first thing I would do would be to get rid of my rifle as quickly as I could,so that the unarmed enemy couldn't take it from me and kill me with it!” The soldiers practiced__.
A、before being instructed
B、after being instructed
C、while being instructed
D、two days later
【正确答案】：C
【题目解析】：根据文段描述，年轻的士兵们正在接受现代战斗方式的训练，其中一个训练内容是观察两位教官如何仅使用空手夺走对方手中的刀和步枪。随后，在训练这些年轻士兵亲自进行这些动作之前，两位教官向他们提问，以检查他们是否理解了之前展示的内容。这表明士兵们在接受提问和考虑如何回答时，实际上是在接受训练的过程中。 A选项“before being instructed”表示在得到指导之前，这与文段描述不符，因为士兵们已经观察了教官的示范。 B选项“after being instructed”表示在接受指导之后，但文段中提到提问发生在士兵们亲自训练之前，所以这不是正确答案。 C选项“while being instructed”表示在接受指导的同时，这符合文段中士兵们正在接受训练并同时被提问的情境。 D选项“two days later”表示两天后，这与文段描述的时间线不符。 因此，正确答案是C，表示士兵们是在接受指导的同时进行练习的。
