Sentence (II): In the given sentence, the word 'steady' is used as an adjective which means worthy of one's trust. The adjective 'steady' is modifying the noun 'woman'. Hence, the use of the word 'steady' as an adjective in this sentence is appropriate.
Sentence (III): In the given sentence, the word 'steady' is used as an adjective which means not undergoing a change in condition. The adjective 'steady' is modifying the noun 'breezes'. Hence, the use of the word 'steady' as an adjective in this sentence is appropriate.
