Since the sentence says that 'the girl sees the boy, but doesn't _____ anything', It is safe to say that dice is not the correct answer. Dice translates to "he says," so would that make sense if the sentence translated to 'the girl sees the boy, but doesn't he says anything,' nope. habla translates to "speak." If we put habla into the blank it simply translates to 'the girl sees the boy, but doesn't speak anything." this is correct.
