Answer 2

Unlike the Portuguese, who had rounded Africa and were sailing east toward Asia, Christopher Columbus decided to sail WEST. His decision was based on his estimates of the EARTH'S circumference and the sizes of ASIA and EUROPE. Unfortunately, Columbus UNDERESTIMATED the former and OVERESTIMATED the latter. Although this resulted in a much longer voyage than he anticipated, his estimates probably helped convince FERDINAND and ISABELLA, the two Spanish monarchs who sponsored his voyage.
