Question

Which words in the sentence make up the adjective phrase? Which word does the adjective phrase modify?

Answer 1

An adjective is a descriptive word, it describes a noun, which is a 'name' word (i.e: the name of an item, the name of a place; e.g: shoes are the name of the things you wear on your feet, 'shoe's' are the noun)

the 'descriptive' word, the adjective, is something which tells you more about the noun.

therefore, the answer should be: a) with the pink spots; modifies butterfly

because 'with the pink spots' describes the noun, the 'butterfly'.
