Option 1 -> The passage explicitly states "They asked admiringly" which directly indicates admiration, and "proficiency" aligns with the snake charmer's description of "his power over snakes."
Option 2 -> The passage shows no evidence of fear; instead, people were curious and impressed. "Experiments" is irrelevant to his proclaimed abilities.
Option 3 -> While possible, "admiringly" in the text specifically points to admiration, not general excitement. "Precision" is not mentioned in his claims.
Option 4 -> No anxiety is described; the people were impressed. "Pride" doesn't fit as the blank requires what he claimed about his ability, not an emotion.
Hence, Option 1: admiration; proficiency -> The passage clearly states "They asked admiringly" when the snake charmer spoke about his abilities, and his proclaimed "power over snakes" reflects his proficiency in capturing them -> correct
