The Age of Exploration: Chapter 4, Exercise 3 — Possible Solution
======================================================================

ACHIEVEMENT
The first circumnavigation, the first European crossing of the Pacific, the
discovery of the Strait of Magellan, and reaching the Moluccas, the original
objective.

COMMERCIAL VALUE
The Victoria returned with 26 tons of valuable cloves, but the source says the
extremely long route proved commercially impractical for regular trade.

DIFFERENCE
An achievement can be historic without being repeatable or profitable.
