[求助]as well as和and的区别

25. Europe’s travel industry is suffering as a result of a sluggish economy, a stretch of bad weather, as well as the chilling effects of terrorist activity that is persistent.

(A) as well as the chilling effects of terrorist activity that is persistent

(B) and the chilling effect of terrorist activity that is persistent

(C) but persistent terrorist activity has had a chilling effect too

(D) and the chilling effects of persistent terrorist activity（D）

(E) as well as the chilling effects of terrorist activity that persists

The best answer for this question will begin with and because the phrase the chilling effects is that last of three parallel elements in a list, which should follow the form “X, Y , and Z.”
            A and E are incorrect because as well as cannot replace and in such a list.
        Moreover, these answer choices are wordy and suggest without warrant that there is terrorist activity that does not affect Europe’s travel industry because it is not persistent. （？？？）B amends only the first fault. C is incorrect because and, not but, should precede the last element in an inclusive series; in this case, but introduces an independent clause that deviates from the structure of parallel noun phrases.
        （不平行）D is correct for this easy question
