Nowhere in Prakta is the influence of modern European architecture more apparent than in its government buildings。
我认为,不倒装的话结构应该如下,
The influence of modern European architecture is more apparent (at or on or in) nowhere in Prakta than (at or on or in) its government buildings (in Prakta).
因为nowhere是副词,所以前面不加介词,buildings前必须补上介词。
所以需要确认一下:答案为“in its government buildings",但并不是说它和"in Prakta"比较,而是和nowhere并列!!
从含义上讲,用"on"或者"upon" it's government buildings 更合适。(influence on sth....)
