Careful-reading: Activity 5 on Page 18
Answers: 1. Because it has the concept of “rebirth” and it was as if Europe was waking up after the long sleep of the Middle Ages. 2. It took place in the 14th – 16th century in Italy. 3. The arrival of the Europeans in America, the development of trade and the changes in idea about religion.
