The discovery of alligator bones in the ruins of Haojing, part of the capital of ancient China's Western Zhou dynasty (1046-771 BCE), helped archaeologists visualize an era in which large lakes had existed in now currently more arid regions.
A. in which large lakes had existed in a now currently more arid region
B. in which large lakes existed in what is now an arid region
C. when large lakes existed where there is a region now arid
D. when large lakes had existed in a current arid region
E. when large lakes existed in a region now that is arid
Choice A: This answer choice features a redundancy in its use of the phrase "now currently"; both "now" and "currently" convey the exact same information. Thus, this answer choice is not a very good one.
Choice B: This answer choice is the most concise one and conveys the intended meaning of the sentence. Thus, this answer choice is correct.
Choice C: This answer choice is highly awkward due to the use of the phrase "a region now arid". Thus, this answer choice is not a very good one.
Choice D: This answer choice incorrectly uses the adjective "current" to describe another adjective; the appropriate term to use in this context is the adverb "currently". Thus, this answer choice is incorrect.
Choice E: This answer choice is awkward due to the use of the poorly constructed phrase "now that is arid". Thus, this answer choice is incorrect.
Hence, B is the best answer choice.All the best!
