The answer is C.

The sentence describes Leger's reaction to New York, stating that although the city exhilarated him, his initial response was not a complete or absolute form of exhilaration.

Blank (i):
A. unspontaneous: This choice suggests a lack of spontaneity or naturalness. However, the sentence conveys that Leger's initial reaction was not simply lacking spontaneity; it was bothered by the stunning verticality of New York.
B. unintentional: This term means not done on purpose. Leger's reaction, described as being bothered, suggests a deliberate emotional response rather than something unintentional.
C. unqualified: In the given context, "unqualified" is used in the sense of being absolute or complete. Leger's reaction to New York was not absolute exhilaration; instead, he was bothered by its stunning verticality. This option aligns with the idea that his initial reaction had some reservations despite being exhilarated overall.
D. unhopeful: This term suggests a lack of hope, which does not accurately capture the nuance of Leger's reaction to New York.
E. uninterested: This choice means lacking interest or enthusiasm. While it captures the general idea of a less-than-positive reaction, it doesn't fully convey the specific nature of Leger being bothered by the verticality of New York.
