问题 Our knowledge of the pains animals feel can be obtained through
The author seems to agree that

选项 A、animals may feel pain.
B、only human beings can feel pain.
C、we can’t tel1 what pain means to an animal.
D、human beings can learn from animals to avoid pain.

答案A

解析 主旨题。在文章的结论部分,作者指出"瞳孔、脉搏和血压的反应只有个别情况下是在没有经历痛感时发生,在未受损动物身上这些反应表明它们在经历疼痛"。因此,作者的观点应为"动物可能会感觉到疼痛"。"只有人类能感觉疼痛"与本文主旨相反,"我们不能判定疼痛对动物意味着什么"和"人类能从动物那里学会避免疼痛"未在文中涉及,也不是可以直接推出的结论。
