旧PREP125 VS 31---奇怪啊。。。continue怎么有进行时了？

這個是這樣的
劃線部份絕對不可能叫你用ing而且不能和2個時態連用
題干中的話你可以無視以上規則
做題規則只是幫助我們解題而並非正規語法規則

很多TX都说continue是不可以用进行时的，比如本题笔记就是这么写的：
125.The computer company registered a $16 million net loss for the year, largely because it was profitable only overseas, where much of their profits were used for paying higher taxes, while continuing to lose money in North America.
(A) where much of their profits were used for paying higher taxes, while continuing
(B) where much of their profits went to pay higher taxes, as they continued
(C) where much of its profit went to pay higher taxes, while it continued
(D) with much of their profits going to pay higher taxes, while continuing
(E) with much of the profit used for paying higher taxes, as it continued

动词形式-现在进行时，有些动词（表示状态或感觉的词，或者表示极短暂的动作）一般不用现在进
行时，比如：declare, recognize 等，continue 是表示状态的动词，不用现在进行时态。
还有好些题，都会提到这句话。

但是！我发现PREP题目非划线处有用continuing的！
31.According to some economists, the July decrease in unemployment to the lowest level in two years suggests that the gradual improvement in the job market is continuing.

我不知道continue到底可以用进行时么？
谢谢大家指教！！！
