The Biological Approach
Numerous biological structures and chemicals appear to be involved in aggression.One is the hypothalamus,a region of the brain.In response to certain stimuli,many animals show instinctive aggressive reactions.The hypothalamus appears to be involved in this inborn reaction pattern:electrical stimulation of part of the hypothalamus triggers stereotypical aggressive behaviors in many animals.In people,however,whose brains are more complex,other brain structures apparently moderate possible instincts.
According to paragraph 2,what evidence indicates that aggression in animals is related to the hypothalamus?
○Some aggressive animal species have a highly developed hypothalamus.
○Artificial stimulation of the hypothalamus results in aggression in animals.
○Animals behaving aggressively show increased activity in the hypothalamus.
○Animals who lack a hypothalamus display few aggressive tendencies.
我在C和D之间犹豫,还有就是,这类题有什么注意事项吗?
