GDW答案是C或者AC争议，Manhattan网站上Staff的答案是A，C错的原因是：
[size=1.3em]the connection between "predicted" and "would" is just fine. However, we start the sentence with "Since February." This phrase indicates an ongoing action -- as a result, we want to use the present perfect tense: "have been predicting for weeks." Furthermore, to use the past tense "predicted" would indicate that they are no longer making such a prediction -- again, not what we want here, logically.
