Which words in the sentence make up the adjective phrase? Which word does the adjective phrase modify? This rocky canyon in the desert is not the deepest canyon or the widest.
a. rocky canyon; modifies deepest
b. in the desert; modifies canyon
c. rocky canyon; modifies desert
d. is not; modifies plateau
I'd say the correct answer is B, because 'in the desert is part of the subject/noun 'canyon', and modifies it, that is, refers to it, describes it in more detail.
