A puzzling discovery

At last, on September 6th, everything was ready again. Once more the ships set out to sea.
He wanted to sail west from Europe, west across the Ocean Sea, west to the lands of Asia called the Indies. He would find a sea route to the pearls, gold, spices, silk and perfumes of the Indies.
Then, on the evening of September 9th, the last trace of island disappeared. Now the voyage had truly begun.
And in this world the only known lands were Europe, Asia and Africa. Together they formed a giant island surrounded by the Ocean Sea.
Their names were the Nina. the Pinta and the Santa Maria. Aboard them there were ninety men under the command of Columbus.
His name was Christopher Columbus, and he was a sailor with a bold plan. (1)______. For year traders had carried these riches overland to Europe. Now, with land routes closed by war, trade had stopped.

Columbus studied maps and read geography books. He asked the experts for advice. He planned, and when he was ready he began to search someone who would give money to make a trip. Finally he found a backer in Isabella, Queen of Spain.

And so it happened that on the morning of August 3d, 1492, three small ships sailed from Palos, Spain. (2)_______________ .

But the voyage was not yet really under the way. On the third day out, the Pinta's rudder broke. The fleet had to stop at the Canary Islands for repairs. (3)_________________.

At first the winds were light, sometimes dying altogether. For the few. days the men could still sea the mountain peaks of the Canary Islands. (4)__________ . They were sailing into the unknown.

In his cabin Columbus had a chart that he had drawn himself. Like the best maps of his day, it showed a world much smaller than the one we know. (5)__________________
