The Arthritis Research Institute of America advises women of color that they have twice the likelihood to get osteoarthritis of the knee as do White women.

 

1. that they have twice the likelihood to get osteoarthritis of the knee as do White women
2. that they are twice as likely as White women to get osteoarthritis of the knee
3. that their likelihood of getting osteoarthritis of the knee is twice as much as White women
4. of being twice as likely as White women to get osteoarthritis of the knee
5. of having twice the likelihood of getting osteoarthritis of the knee as White women

貌似不难哦，但就是没做对，在A和B之间选了A，结果答案是B，不知道A为什么不对啊？

B:they & white women 比较对等

A如果用as  do至少前面有都好

另外，twice as...as或者twice  than

个人意见。

Hi,谢谢你的提示，A的话应该是they have as twice the liklihood...as do White women.这样的话应该对了。
