问题 New data has______that the damage to the ozone layer is not confined to the southern hemisphere.
选项 A、ratified
B、confirmed
C、assured
D、approved
答案B
解析 B项“confirmed证实”符合题意。如：Please confirm your telephone message by writing to me．(请给我来封信，好进步证实你在电话中传达的消息。)其他三项“A项ratifled批准，许可；C项assured保证；D项approved同意，赞成”都不正确。本题意为“新的数据证实臭氧成层的破坏并不限于南半球”。因此B项为正确答案。
