Which one is the correct answer
 1 Listen my children and you shall hear
 Of the midnight ride of Paul Revere,
 On the eighteenth of April, in Seventy-five;
 Hardly a man is now alive
 5 Who remembers that famous day and year.
 He said to his friend, "If the British march
 
By land or sea from the town to-night,
 
Hang a lantern aloft in the belfry arch
 
Of the North Church tower as a signal light,--
 10 One if by land, and two if by sea;
 And I on the opposite shore will be,
 Ready to ride and spread the alarm
 Through every Middlesex village and farm,
 For the country folk to be up and to arm."
 15 Then he said "Good-night!" and with muffled oar
 Silently rowed to the Charlestown shore,
 Just as the moon rose over the bay,
 Where swinging wide at her moorings lay
 
The Somerset, British man-of-war;
 
20 A phantom ship, with each mast and spar
 Across the moon like a prison bar,
 And a huge black hulk, that was magnified
 By its own reflection in the tide.
 Meanwhile, his friend through alley and street
 25 Wanders and watches, with eager ears,
 Till in the silence around him he hears
 The muster of men at the barrack door,
 The sound of arms, and the tramp of feet,
 And the measured tread of the grenadiers,
 30 Marching down to their boats on the shore.
 Then he climbed the tower of the Old North Church,
 By the wooden stairs, with stealthy tread,
 To the belfry chamber overhead,
 And startled the pigeons from their perch
 35 On the sombre rafters, that round him made
 Masses and moving shapes of shade,--
 
By the trembling ladder, steep and tall,
 To the highest window in the wall,
 Where he paused to listen and look down
 40 A moment on the roofs of the town
 And the moonlight flowing over all
 What did Paul Revere tell his friend to do if the British were going to attack by sea?
 A) Hang two lanterns in the belfry arch. 
 B) Hang one lantern in the church tower. 
 C) Signal those in the North Church tower. 
 Eliminate
 D) Ride through the country to spread the word.
