Other non-dominant males were hyperactive; they were much more active than is normal, chasing others and fighting each other.
【正确答案】
D
【答案解析】在句中hyperactive的意思是“极度活跃的，亢进的”。四个选项中hardlyactive的意思是“几乎不活跃的”；relatively active的意思是“相对活跃的”；extremelyinactive的意思是“极度不活跃的”；pathologically active的意思是“病态性地活跃的”。只有D与题中词意思接近。
