问题：

在探究串、并联电路规律的实验中，小明同学进行了如下操作：

（1）把两个标有“2.5V、0.3A”字样的小灯泡L₁和L₂串联起来接到电源上，使灯泡发光（如图所示），然后分三次接入电压表，分别测定AB、BC、AC之间的电压并记入表1中。

（2）把上述两个灯泡改接成并联后，接到同一个电源上，使灯泡发光（如图所示），然后分三次接入电流表，分别测定A、B、C三处的电流并记入表2中。

表一表二

	L_AB	L_BC	L_AC
电压（V）	1.25	1.25	1.50

	I_A	I_B	I_C
电压（V）	0.30	0.29	0.58

请你评估：

（1）表1中测量结果有一个量是错误的。错误的是，判断的依据是。

（2）表2的测量结果是否可能？谈谈你的观点。

bullets(子弹)are flying    13   your ears, you think: 'What am I doing here? I'm not going to do this
again.' But that feeling    14   after a while and when the next war starts,  you'll be    15   ."

of yourself." Does he ever think about dying? "Oh,    18   , and every time it happens you look to the
sky and say to God, 'If you get me out of this, I    19   I'll never do it again.' You can almost hear God
    20   , because you know he doesn't believe you."
