Cevap
the constant difficulty of stringing copper wire over vast, arid plains.
The sentence uses the correlative conjunction pair 'not only... but also...' to link two challenges faced by the labor crews. The first challenge is phrased as a noun phrase: 'the daunting task of transporting thousands of heavy wooden poles across rugged mountain ranges.' To maintain parallel structure, the second challenge must also be structured as a noun phrase. The option stating 'the constant difficulty of stringing copper wire over vast, arid plains' matches this structure perfectly by using a noun modified by an adjective and followed by a prepositional phrase starting with 'of'.
