选项 A、sounds
B、voices
C、comments
D、studies
答案 B
解析 词汇题。词义辨析题。voice可表示“意见，看法”，如：Our group rejected the pro—posal with one voice．我们小组一致反对此提议。此处表示“不同看法”，与前面第二段提到的Contrary to some scientific opinion(与一些符合科学的意见相反)正好形成呼应，因此，符合题意，为正确答案。sound意为“声音，响声，很明显的吵闹声、嘈杂声”，如：Have you heard a hollow sound?你听到一声沉闷的声响了吗?sound不能表示“意见”，因此，不合题意。
