Humans, like other animals, ______ with each other through commu

Humans, like other animals, ______ with each other through communicative behavior by means of signs or symbols. (act)
【正确答案】:interact
【题目解析】:该题中空格处需要填入的词作谓语,故需要用动词形式,根据句意此处不能用动词act或react,而要用interact“互动,相互作用”。该句的句意为“人类就像其他动物一样,通过诸如手势或符号的交际性行为进行互动。”
