Final answer:
The adjective in the sentence is 'sharp,' describing the curve, and the adverb is 'too,' qualifying how fast Carla skated.
Step-by-step explanation:
In the sentence 'Carla fell when she skated too fast around the sharp curve,' the adjective is 'sharp,' which describes the curve, and the adverb is 'too,' which qualifies the adverb 'fast,' indicating the manner of skating. Adjectives describe or modify nouns and pronouns, giving more information about them. Adverbs modify verbs, adjectives, or other adverbs, often ending in '-ly,' but not exclusively, as seen in this case with 'too.'
