Which lines from "the listeners" best support the inference that the traveler was gone longer than the people in the house expected?
a "'tell them i came, and no one answered,
that i kept my word,' he said."
b “'is there anybody there? ' said the traveler,
knocking on the moonlit door; "
c "and he felt in his heart their strangeness,
their stillness answering his cry,"
d "but only a host of phantom listeners
that dwelt in the lone house then"
