请教Prep中的2个问题

我做的prep分成两个部分，分别是151和169题，在置顶帖中找不到对应的讨论，望XDJM们告知如何能找到讨论..先问了再说

28. Polio, although it is eradicated in the United States, it continues elsewhere and is able to be brought into the country by visitors.

(A) Polio, although it is eradicated in the United States, it continues elsewhere and is able to be

(B) Polio, although eradicated in the United States, it still continues elsewhere and can be

(C) Although still continuing elsewhere, polio has been eradicated in the United States and could be

(D) Although having been eradicated in the United States, polio still continues elsewhere and is capable of being

(E) Although eradicated in the United States, polio continues elsewhere and could be
    

正选是E，想问一下 一般的动词continue可以和情态动词could并列吗？

(A) that CEO's now earn an average of 419 times more pay than blue-collar workers, compared to a ratio of 42 times

(B) that, on average, CEO's now earn 419 times the pay of blue-collar workers, a ratio that compares to 42 times

(C) that, on average, CEO's now earn 419 times the pay of blue-collar workers, as compared to 42 times their pay, the ratio

(D) CEO's who now earn on average 419 times more pay than blue-collar workers, as compared to 42 times their pay, the ratio

(E) CEO's now earning an average of 419 times the pay of blue-collar workers, compared to the ratio of 42 times

正选是C，想请教一下倍数词的比较

419 times more than 和 419 times the pay of 是表示一个意思吗？，我怎么觉得419 times more than有可能表示419倍有可能表示420倍？如果这样就会有歧义。

那什么情况下 ，倍数词 + more than 和 倍数词 + as as表示一个意思呢？？望朋友们指教！谢谢！

第一个我在OG中没搜到相关用法，但是我觉得这样并列没有任何问题。而如果情态动词在并列成分的前面一个时，可能会产生情态动词修饰不修饰后一个动词的问题。

第二题以前讨论过。BY中没有...times more than的用法，只有...times as..as,以及...times the+n.的用法，但是prep有一题用的...times more+adj.+than.有没有...times more than说不好。。
