Which word in the sentence does the underlined phrase modify? * During the tour*, we bought souvenirs at the gift shop. A. gift B. shop C. bought D. souvenirs

C. Is the correct answer here - bought is based on the root verb 'buy or to buy' but its sense in the sentence is set against the framework of a time from the phrase with the word 'During' and so the word of choice must become 'bought'.
