Question

choose the word that best completes the sentence. the canine police unit was forced to retire one of its contraband - sniffing dogs, rex, when he suffered an injury to his nose and couldnt smell anymore.

Explanation:

'Well' is an adverb that can describe a physical state. Here, it refers to the dog's ability to smell. 'Good' is an adjective and would not be used to modify the verb'smell'. Since the dog can no longer smell due to injury, 'well' is the appropriate word.

Answer:

well
