longman ibt Reading Pre-test problem 4 ? - 英檢

我是新新手 XD
剛翻開longman然後做了第一部份 Reading 的 Pre-test
題目是，Aggression，對了答案以後，對第四題的答案有些疑問
第四題是要選出第二段中反白句子的主要意思，句字是：
Theories about the causes of aggression cover a broad spectrum,
ranging from those with biological or instrinctive emphases to those
that portray aggression as a learned behavior.

我選選項(C)：
Various theories about aggression attribute it to either natural or learned
causes.

但答案卻是選項(B)：
Theories that consider aggression biological are more accepted than
those that consider it learned.

請問一下，這題的解答是不是有誤呀？

PS.很多關鍵字不懂，文章真的也看不懂，還有好多要練要學呀...

Thanks!
