OG里AGGRESSIVE 那个题真的很纠结， 谁帮我解释一下啊谢谢

Paragraph
2: 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.

    

 

    

1.
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.
