"an officer of the federal force, who in a spirit of adventure or in quest of knowledge had left the hidden bivouac in the valley, and with aimless feet had made his way to the lower edge of a small open space near the foot of the cliff, was considering what he had to gain by pushing his exploration further."

the description of the officer's spirit of adventure foreshadows

a.) that he will lie to the union commander.

b.) that he will seriously injure himself upon falling.

c.) that he will be the only observer of the horseman's fall.

d.) that he will question carter's part in the strange incident.

d is not the right answer just saying i took the test and got d wrong

I would contend that the right answer is the C) that he will be the only observer of the horseman's fall.

Explanation: Just to elaborate a little on the answer, it can be added that by making his way "with aimless feet" and "pushing his exploration further," the officer had the potential chance of witnessing something unexpected and adventurous. And this he did, when he saw the horseman in the sky. He did hurt himself in his shin when he saw the man on horseback riding through the air, but not seriously, and this description of his spirit of adventure does not necessarily suggest that he will lie to the commander.
