1) Explanation

Analyzing Blank (i):
The phrase "had been traveling by foot for twelve hours with no food or water" describes an extremely exhausting situation. We need a word that describes hikers who are severely weakened or exhausted.
- A. enervated: Means feeling drained of energy or vitality; weakened. This fits the context of long, foodless, waterless travel perfectly.
- B. morose: Means sullen and ill-tempered; gloomy. While they might be gloomy due to exhaustion, "morose" describes their mood, not their physical state of being drained, which is the primary consequence of twelve hours of travel without sustenance.
- C. imperious: Means assuming power or authority without justification; arrogant and domineering. This has no relation to the physical state of exhausted hikers.

Therefore, for Blank (i), enervated is the best fit.
Analyzing Blank (ii):
Samantha fears she would become "dangerously $\qquad$ if she had to continue any longer." Given the "no food or water" context, her fear would be related to the consequences of prolonged lack of water.
- D. timorous: Means showing or suffering from nervousness, fear, or a lack of confidence. This describes a state of mind, not a physical danger from lack of water.
- E. parched: Means dried out with heat; extremely thirsty. This directly relates to the lack of water and the physical danger of dehydration.
- F. lugubrious: Means looking or sounding sad and dismal. This describes a mood, similar to "morose," and doesn't fit the physical danger implied by "dangerously."

Therefore, for Blank (ii), parched is the best fit.
