Answer:
Dorothea Lynde Dix (1802-1887) was an author, teacher and reformer. Her efforts on behalf of the mentally ill and prisoners helped create dozens of new institutions across the United States and in Europe and changed people's perceptions of these populations.
Explanation:
The Portuguese were among the first Europeans to explore the
seas beyond Europe. Henry the Navigator urged his father, King John I, to
conquer the port of Ceuta in Northern Africa. He also sponsored the development
of the Caravel, a sailing ship that is lighter and faster than most ships at
that time. Use of caravels enabled sailors to travel further and with more
provisions, and the light draft enabled Portuguese sailors to explore shallow
rivers and waters. He also sponsored explorations to Madeira, Azores, and West
Coast of Africa.
