Twenty thousand years ago, the Earth was held in thrill by relentlessly probing fingers of ice 
that drew power from frigid strongholds in the north and crept south-westward to bury forests, 
fields, and mountains. Landscapes that were violated by the slowly moving glaciers would 
carry the scars of this advance far into the future. Temperatures plummeted, and land surfaces 
in many parts of the world were depressed by the unrelenting weight of the thrusting ice. At the 
same time, so much water was drawn from the oceans to form these gargantuan glaciers that sea 
levels around the world fell by three hundred and fifty feet, and large areas of the continental 
shelf became dry land. This period of the Earth's history has come to be called the Ice Age. In 
all, about eleven million square miles of land were covered with ice. The Ice Age terminated 
about fourteen thousand years ago when the ice sheets began to retreat. It took about seven 
thousand years for the ice to retreat to its present level. 
1.Which of the following would be the best title for the passage ? 
A) The Frigid Strongholds of the North.
