英语完形填空（选择题）
The two brothers (ingenious,ingenuous) each other; one is impulsive,the other,cautious.
请问应该选哪个?并解释为什么要选那个.
我真是把题抄错了。the correct ones should be as follows:
1.The two brothers( compliment,complement) each other; one is impulsive the other,cautious.
2.The boy gave an(ingenious ingenuous) account of what had happened,concealing nothing.
实在抱歉啊，对不住楼下两位回答者了！小女子再此感谢两位的支持！
