Read the following poem and answer the question that follows.
 "I Like to See It Lap the Miles" by Emily Dickinson
 I like to see it lap the miles,
 And lick the valleys up,
 And stop to feed itself at tanks;
 And then, prodigious, step
 Around a pile of mountains,
 And, supercilious, peer
 In shanties by the sides of roads;
 And then a quarry pare
 To fit its sides, and crawl between,
 Complaining all the while
 In horrid, hooting stanza;
 Then chase itself down hill
 And neigh like Boanerges;
 Then, punctual as a star,
 Stop—docile and omnipotent—
 At its own stable door.
 This poem describes a train as if it were a horse. Examine the imagery of the stanza in bold. What does it describe?
 The rumbling a train makes as it passes by
 The smell of train tracks after a train has gone
 The sound a train makes as it blows its horn
 The feeling of being on a train for a vacation
