问题 Statements presented as fact in a patent application are(i)______unless a good reason for doubt is found. The invention has only to be deemed "more likely than not" to work in order to receive initial approval. And, although thousands of patents are challenged in court for other reasons, no incentive exists for anyone to expend effort(ii)______the science of an erroneous patent. For this reason the endless stream of(iii)______devices will continue to yield occasional patents.

答案A
解析 The paragraph appears to be explaining some odd or unexpected aspect of the patent process. The third sentence helps to clarify what this aspect is; it discusses challenges to patents. The only choice for Blank(ii)that is concerned with challenging a patent is "debunking," since "corroborating" and "advancing" suggest support instead. This in turn provides the answer for the third blank, since the preceding sentence does explain how "bogus" devices may nonetheless get a patent. And we can also now better understand the first sentence—it too must help explain how bogus devices get patents, which it can do only if the blank is filled with "presumed verifiable," suggesting that patent applications are taken at face value and not dismissed out of hand nor subjected to careful scrutiny.
