Choose the best alternative for the underlined part 1.
A. NO CHANGE B. one finally ultimate C. one final D. one last final
The best answer is C, which concisely conveys the idea that the practice landing referred to was the last one in a series. In contrast, the other choices are redundant. Choice A belabors the point that "the final performance" was indeed the "last" performance (and confusingly suggests that there was more than one performance of a single landing). Choice B pointlessly repeats the notion of finality in the redundant phrase "finally ultimate" (and confusingly suggests that all the landings strove to be ultimate, but only the last landing succeeded). Choice D is simply redundant because the words last and final in the sentence are synonymous.
