OE
Quote:
Because this sentence starts with the word “While…” in a modifier, you should immediately start looking for the portion after the comma to contradict the first half of the sentence. The first half talks about the substantial cost of the project, so in the second half you want two words that show that the cost is justified, or that in context it’s not as high as it seems.That should lead you to choices B, D, and E, where the real work begins. Because “imprudent” connotes “too much money” and “excessive” suggests the same, those are the correct answers, B and D. Both of them show that while the price is high, it’s not too high given the large costs savings that will result from them.
