解析：The keys to this sentence are the word “Despite,” the words “human in scale,” and the words “not remote and larger than life.” The word filling the first blank has to be one that would relate closely to something that seems “larger than life.” The word filling the second blank has to fit with “human in scale.” If you focus on just one of the two blanks, you will be able to eliminate several choices before you even think about the other blank.
