Question

During the early hours of the morning, a wild blizzard followed
the frost. It was impossible to go on. For three days, tormented
by anxiety, they remained stranded in the post-house, but on the
fourth day the weather cleared. The troika went off again, the horses
struggling through deep snowdrifts on to the next post house. The
weather continued to improve. There were clear nights and the frost
was bearable. One evening the troika set off for a village that was
nearby and boasted better conditions than most stations. It was a
peaceful starry night. The fresh, sturdy horses ran cheerfully along the
moonlit path when suddenly for no apparent reason they bolted at
great speed.
‘Derzhites! Volki! Hold on! There are wolves,' Stepan called out.
The horses had sensed before the passengers that there were wolves
nearby. None were seen at first, but as they peered into the darkness
they saw the small green lights of eyes weaving through the trees
and moving in the same direction as the sledge. Yenya's mother,
who had a superstitious fear of wolves and firmly believed they were
possessed by some evil power, crossed herself. 'The power of the
Cross protect us,' she said, using the prayer that wards off all evil.
The horses, maddened by fear, flew out of control and raced on. The
troika bumped and swayed over the frozen ruts. At any moment it
could turn over and they would be thrown out and perhaps killed.
There was the added fear that the wolves would run to where the road
and the wood met and cut them off from the village. Then in the dip
of the road, there came into view the row of orange lights from the
cottages. There, the villagers had heard the urgent ringing of the bells
on the troika. A loud chorus of dogs, barking and howling, shattered
the stillness of the night. The troika rushed through the open gates of
the station and stopped inside the safety of its walls. The horses stood
trembling in clouds of steam, foam dripping from their mouths.
