The Correct Option is A

Solution and Explanation

Step 1: Read the whole sentence containing blank (46). It praises an author who does not let political disputes distort a factual account of the planet's climate and biodiversity.
Step 2: Since the surrounding tone is approving, the missing word must be a positive one, which rules out "Boring," "Dreary," and "Tedious" right away, since those all describe an unpleasant reading experience.
Step 3: Between "Refreshing" and "Stimulating," think about what exactly is being praised. Most books on politically charged topics like climate change end up shaped by political leanings, so a book that avoids this is a welcome change from the norm. "Refreshing" captures that sense of relief from the usual politicised writing, whereas "Stimulating" only says the book is intellectually exciting, without capturing the contrast with typical politicised accounts.
Step 4: The passage's whole point in this sentence is the pleasant surprise of finding unbiased writing on a heavily politicised subject, which "refreshing" expresses best.
